No. Like if you say you've never seen them before, is it that you don't think you've learned about it? Or is it that, okay, you don't think you've learned about it in class, in school? How about like when you talked with the other students, did they say similar things or how did they find it? But king is I never do this question before, so I don't know how to do for I mean, it's for the common no, which subject. I think it's a country Yeah, country. Okay. And when you asked your friends, were they also like, Yeah, I don't think we learned that. Like Yeah Yeah, it's like it. Okay. Did you manage like after realizing you don't think you learned nit before? Did you ask like your teacher? No. Do you think is that because you haven't seen them yet or you didn't think of asking it? Because I don't think, okay. Maybe next time you see your teacher ask them about those questions, like especially if you haven't learned them in class, I think it's quite important to clarify with them. Yeah. Yeah, okay, I'll make a note for you so you don't forget to do that. So just write to this. Also, I wanted to give you a little tip. I saw this this week. If you you know how before you said it was the long answer questions that you didn't really like. Do you remember that? No. Okay. When we looked at questions, it was normally the ones we you had to write a lot where you were like, Oh, like you didn't like those kind of questions. I don't know if it still the case. Do you get what I mean? No. Like exam questions where you have to write paragraphs? Oh, Yeah, Yeah. So I realize instead of writing paragraphs, if you want, you can write bullet points. And maybe that will be like. More approachable. Do you see what I mean? Yeah, I know. Yeah. Okay. So that could be helpful, right? Is there anything specific you want to do? We're Physics Today. If not, we can just continue with book. I'm not the book today at high school. Okay. Should I put should I use my copy and then I can put it on the on the blackboard. Okay. Also, how was your homework? Like this time we did question practice for homework. Did you how did you do? Used to like reverse the exam so you exited for a bit. So can you repeat what you said? I say I used a long time to revise the exam, so I'm not finished my homework. Okay, that's okay. Don't worry. Right, let's do some reading then. So we're on page 37. I wait. What was matter? I remember like when I asked about homework before, you know how over the Christmas break you or like Christmas January period, you are doing it yourself, like reading through things. But our first session back you said that you didn't really understand what you read, right? Yeah, Yeah. Okay. So should we start at an earlier page? I'll show, I'll show you what pages we have and we can see. Actually I'm a nubiology physics. So page 28 was about parallel circuits. Do you remember? Yeah, I remember. Are you happy with those? Or shall we start here? Yeah. Like do you what from the two options do you want to start a parallel circuits? Or are you happy to move on? Yeah, I think I'm happy to move around. Okay. The next bit is about investigating resistance. Are you happy with that? Yeah, okay. Electricity in the home. Are you happy with that? Yeah, okay. Power of electrical appliances. That's like energy transferred and power. Are you happy with that? Yeah, okay. What about the national grid? National quethe national grid is how electricity is distributed. Good. Okay, let's start on this page. Let's start on the national grid. Is this big enough for you to see? Are the words okay, not too small? Yeah, I see. This is okay okay. No, what I mean? Like you can read it here. It's a national girl passing. I never said this before, so. Okay, that's good. We can read about it then. Do you want to start reading? Yeah, nice. In you do know national. Grid. Great. Yeah, perfect. Nice. National grade. In did know, however, you pay for your isn't national good, that that good is to you. Electricity is a is a. Is distributed. Or to say distributed distributed. Right distributed or what I mean, I don't know, distributed. What I mean like. Spread out. Thank very love. Yeah shadow about. Ated where the national. Gstate. Of a couple couples. What the hell, I don't know. Tables, it's the same as wires. Similar to what cable is, is the same as y. Wise wise what means wise? I've forgot. Like in a circuit, in a circuit. Oh, Oh, Oh, Oh, Oh, okay, okay, I get it. Yeah. Covers and. You want to try and pronounce it. Transformers, Yeah, transformers. That was good. Transformers. So the code going printing. Is a transfer, is electrons powerful? Power station station, how to see this word? Power stations, you did well. I think you Press stations Yeah, like train station tions station the same thing. Oh, it's train stations, power station or power station station tions. Oh, to consumers. The damage anyone who is using electrianywhere on the electriper production has to make damage. What what's what the mean? Electricity production has to meet demand. I think a bit I le, Yeah a little bit afterwards we'll explain it. So read that first, and then if you still don't understand, then I'll talk to it. Do you know what demand is? Okay, demand is how much people want something. So like if you're selling ice cream, if you're selling ice cream and it's a hot day, then demand is going to be quite high. But if it's a cold day, probably demand is low because people don't want to eat cold things on a cold day. Does that make sense? Hmm. Hmm. So. How to say again, please, electricity production has to meet demand. Electrihas to. Be. Are you okay? Are you. Wait, I try to understand this word, which word before the day? Oh, throughout the day. Sell out. Yeah, I'll sell out. Yes, all they it tranused to dipower stations has have to to produce electricity for everyone to have it when they need. Hmm. Power stations often run as well below there may power output, so this space cover ty too two cuwith a. Sugar. Sir. No, all which. This war. You want to. Which means below there the next Maximum Maximum Mozi, like the highest. Highest Yeah. So like if if we had a scale of one to ten. We had a scale of one to ten. The maximum number you can never say is ten because that's the limit. The highest. Whereas the minimum is one lowest. Okay maximum minimum. Maximum power. So they company to cope with going there an. So even if there's an unexpected shutdown of another station. Junexpected. Unexpected. Yeah. Do you know what? Do you know what that means? No. You know what? I never, ever seen this before. You know what it means without the uso. Just expected. If something is expected, what does that mean? Expected. So something expected. Do you know what it means for something to be expected? God, thank you, God. Let's say someone, if you knew it was going to happen or like it was very likely it was going to happen. So like you might have A, I have a friend who is almost always late to every meeting, but when he turns up late, that's expected. But if he turns up on time, that's unexpected. That makes sense. Okay, again. Go to fine. Attack答of another station。Lots of smaller power stations that can start up quickly are also cheapping on down by just in course. Yeah. Read this bit to the yellow box. The box occurs when people gain up in the moment, come home, come home from school or work, and when it starts to get down course outside. Why do you think this happens? Why do you think demand increases at these times? Okay. Think about, well, maybe I don't know if you will do this. Like whenever people come home from work, they normally immediately boil the kettle or turn on the tv or something like that. And the sudden time of everyone suddenly using lots of electricity, that increases demand. And Yeah, this one's more obvious when it starts to get dark or cold, why do you think the demand increases there? Why I think it increases. Do you understand my question? When it starts to get dark or cold outside, why does demand increase mangic? Good. So I told you that when people come home from school, demand will increase because lots of people turn on the tv or boil the kettle and things like that. So what might people do when it starts to get dark or cold, which increases the demand? No idea. What do you do if it gets dark or cold? Do you use any appliances or use eleconmore? For me, Yeah, maybe. Such as a hoof scisis. I've got how to say a word, but that can change the and you you can control, but very simple to use. But it uses electricity. Oh Yeah, Yeah, Yeah. Okay. So think about it. When it's dark or cold outside, you increase demand by using something that uses electricity right now, think about every person on the planet. When everyone uses slightly more electricity, the overall demand is going to increase quite a lot, right? Yeah, Yeah, Yeah. Okay. So I would have answered by saying if it gets dark or cold outside, you'll probably use more electricity to turn on heaters or turn on lights. Or if you were originally planning to go outside, you might stay inside and use like the television or something like that. Yeah. Okay, awesome. Next. Night where the night show group user has pd and low control is correct, no card, okay to transmit the hunger amount of power needed. Union is to high counor high difference as p equal I form the power paid the more up, more so to the. What the hell, you've seen this word before. I know you know it. I don't know. Yes you do. Yes you do. For got, okay, okay, surroundings surrding, Oh, surrounding. Surrounding, that's okay. Yeah okay. Surroundings, I get it. I think you need to read this box, right? Yeah, Yeah isn't national girl transfer energy by bursting the pd up really high, which keeps the countries as lower and as possible, meaning the energy loss to hiding voice and surrounding this much per more. Y of the. Cheaper and more efficient. First. Word. First word word Oh, this one, you also know you know how to say this. I know you know. Think of this one. Okay, maybe my handwriting is bad. Think of this way. Was this worth in town? Potato? What potato? Potato doesn't so much wrong where potato. So this is pronounced initial. So this is. A potato potential where you're missing the end? Okay. Financial definitely changing by the transfer difference. Thing is potato is correct. Potato is not right. Potato difference is changed by the transfer Yeah exactly the difference in potato. Yeah I think focus on the ten when you say this word. Attention. Yeah Yeah, yes, so, so. What I. Mean most means potential definitely is change by the transfer. You know what potential difference is, right? Do you know what? Yeah. So the transformer is a device okay I think you could you continue reading it because this is the title of okay reading okay okay the voltage up the up for 15 transtransmission you transform and big with嗯我just。Next. Is potential difference se it is a 1010. Focus. On the okay potential. Potential potential. Potential potential okay potential difference speed is. It's a. It's an increased. Must mean the inquest increase. Increased increased es what's mean the increased if you have a number like 20, if you increase the number, you'll do like 21 or 22. If you decrease it itbe like 19 or 18, decrease, decrease. I. From the power station, do the transcovers using a step pe up transform as pincrease the. Good, what? What I mean current? Irland, Yeah. Okay, pause for a second. Pause for a second. What's mean the current? I don't pause. Pause. Tell me what owns law Res? Slares. I heard before. Onsource. Source v with which for p equal I times v. Okay, that is a correct equation. But that's not Oh's law. But that is correct. That's a good equation to know that what is ohms law? That's equation for power. That's power equation. Homslow is something else. Counor or Oh lord. Wait are I are equal I times three no v equal I times R I right? Okay, what's your answer? Something's wrong, but I forgot. What are you going with? Helen, what's your answer? My answer. Is when equal times I Yeah, I get it. I don't say like this because I are, but it is R times I okay, now tell me what what do these individual things stand for? What. Are they? What's we? What? What's? What's we how do I understand the worway? Like what is it if you were writing it as words does what is v as a word? We were, we no, have forgot we for example, for example, if I, this is the equation for speed, right? This is the speed equation. And I'll say, s is speed, d is distance. And is. Yeah, so I want you to do the same, but for am's law, tell me what v is, what I is and what R is. Yeah Yeah, okay. We equal items are. It's like a voltage. Conand. Yeah. Bonus question order units. So like for speed, I would per meters per second time, I would say second distance is meters. What are the units for these three? Are you with me? I don't know. Okay, well, let's start with this one. What's the units of voltage? You honor. Thank you. Like if you have a voltage of six, what what do you write after it? What's the unit? Like if I had a, if I had a speed of six, I can't just write six. I have to write 6m per second. So what do you write here for a voltage? No idea. Think of a volmeter. What's the symbol on a volmeter? On the circuit diagrams. What is the Oh, we Yeah so voltage is measured in volts. What what hold about go now. What about current? What's current? Measured it? Hey. What did he say? Hey, Yeah. Do you know what that is called? Absolutely no. Okay, it's helps. Ps, ups, or people call it aperres too, but normally you hear apps. And then finally, what about this one resistance? Bye. How is no有没没。With. Homes? Yeah. Do you know how to write it like a. That's really good. It's. Do you know how to write the symbol? Oh, it can easy. So let's say this for this. Easy, no, no, what's the symbol? Asble assyo? It's I'm just going. To draw it. It's like this, right? What's that? What's that? That's the that's the symbol. That's an own symbol. How to say, well, the actual symbol is called omega, but the unit's called omms. All right. Yeah. So from just looking at the units, you should be able to tell if it's a voltage resistance or a current. Like if I put that, you know it's ten amp, you know that's a current. If we put this, you know it's ten ohms, it's resistant, you know? Right. Yeah Yeah. Anyway, all this was to say, you know what a current is and also voltage is the same as potential difference. It's the same thing. So you know all of these things anyway? Yeah, oops, I probably shouldn't have. Yeah, okay. Anyway, Yeah current you know what current is earthat's this that's I in vehicle's eye. I are. In umslow. And all our lord. Yeah. Sorry, what's what's a question? No, no, I was just saying because you were confused what this word was current. But you know what current is? Because you know om's law current current. Current this one. Yeah Oh I that is that is current so was awword. Because you're confused at this word, but that's the same word current. All Oh, okay, it's. Okay, let's finish this name. Current is decreased, which we talked about here already, okay. Day quiz. Kitis. The same code. Reduced reduced. And reduce okay okay again. Again again at the local council and using a stpping. A step down. Step down transfer form. Okay them don't transform. Well, this warme, which one? This is make the pds safer, safer, safer, safer, safer. I think it all safer. Okay, like more safe. Yeah, okay. Yeah, more safe. For consumer speed deccurrent is increasincrease yes. Okay, final books you got this. 嗯。Energy demand are even increased. The national grid has been working since the 19 thirties and has gone through many exchanges and updates ated to meet increased energy demand, user energy, energy and switching an unneeded. Land offer can help to keep peand diin balance, do Warfor your electricity ability to does as I'm am sure your peroften Remond your. Okay. I want to ask you a question. Just okay, what's a question? You know how like for homeworks, normally you do readings of like page. Let's do another page, right? Yeah. How do you handle reading them by yourself? What I mean by myself? Yeah because for homework, I'm not there to explain stuff for you. So how do you go about doing it? Actually. I. Like how how to. Say I can use the Internet to check the something I don't know. So okay, let's fine then that's good. Like as long as you're checking and not like just skipping over it, then that's fine. Okay. Hi. All right. I will set you. I'll set you your homework. How busy are you this week, coming week? Very paing. Okay, not not busy. Yeah Yeah, not busy. All right, I will try and set you a bit more then. Okay, I'll see you tomorrow. Okay, see you tomorrow. Bye bye. See you, bye.
