This is a topic that many people are looking for. voteyesons.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, voteyesons.org would like to introduce to you A 1500-W heater is connected to a 120-V line. How much heat energy does it produce in 2.0 hours?. Following along are instructions in the video below:
Know how you doing man. Im here lets get started man. You know know what im saying.
So. If you uh knew right here. Okay make sure come right here and subscribe.
And but if you come back then well come back man. You know. This is like a waste of time man.
Its just easy like this man. So easy like that man lets get started. So i see her we have a 2 ohm resistor.
Its connected across the terminal of a belly. So we have a belly. The voltage across the chain.
You know of the battery falls by oh. So the moment you connect the voltage falls by then so what it tells you it tells me that if the voltage dropped by 03. Means that voltage was consumed by battery.
You know what im saying. So now lets draw a simple diagram okay. So lets see lets assume three this is our belly okay.
Lets see this is a battery. Its a rough sketch. Okay.
This is a battery and then we connect to external resist. So theres two ways either i can connect here a small resistor or if you dont want to connect like this another way you can just say okay. Theres my berry here okay.
I said its my berger and i can say like this so ada or the other two eggs okay. So what is that oh 20. Ohms.
So its 20 ohms or for resistor. So if i use this diagram and then say. This is training or eight of the diagram.
Okay so now we have internal resist whenever they have this battery. We have a channel resistor okay. Internal resistor and this external resistance.
Big r. And this external resistor. Bit.
Other. But here we have a chain resistor. So what do they say they say.
12 volts of a battery okay. So i call the team you know of 12 volts of a bell. But this voltage across the terminal of the battery falls by oh.
So now if if if to top and then falls by three means that voltage was consumed by the. Battery you. Know which is.
03 so now im going to say let me take 12 minus. 03. So ill say okay.
So the voltage. Im going to use its going to be 1 12 voltage by. 03.
Voltage and this is going to give me 117. 40. So this is the voltage one left for the voltage.
That im gonna use okay excuse me what im gonna use by the watch of the battery. Me here.
40 of the battery. Let me see what your battery. So the other voltage is the voltage.
The whole system means the voltage of the whole circuit. So lets say this is vertical. Very so lets see what the other footage uh.
Other lets say. Other lets say. All forty.
Oh uh okay. Let me say just a voltage. So.
14 that we will be left with its going to be 113 voltage. So same thing like im trying to do the same thing here for your equal to 113. 40.
Depending. Whichever diagram you use. Its going to give the same amps.
So now so i have the voltage. Which is left you know and then i know that it is like theres a voltage of outsider or the side that is not a bearing okay. Sorry.
Let me just keep silence here a little bit because making noise silence sounds. It shows. My polish so for that case now im going to say from ohms law.
We say from ohms law um v. Equal. To i r okay.
So what is my voltage of the one which is not used by. The battery so 117 voltage lets just say 117. Were going to put unit letter currents you know the current no but i have the so the current that were going to have is going to be.
058 its going to be 0. 5 8. 0585 empty.
Oh. So this is going to be the current off. Which is going to be circulating around the cycle look so this is hakka right so if this is like a second means.
This must be possible the longer. One possible is the current go all this way and come back here. So.
The cardinal is going to be circulated through this cycle. Same here this can be positive because this is longer you know so whatever theres a longest process the current so the current we have is. 05854 okay.
So this current is gonna be through the whole cycle. Okay so now what do you want to see if its about the internal resistance of it of this battery in terms of this battery. Its easy man.
Im gonna get this okay so now im going to say same thing from on below v equal to i but now resistance so voltage voltage now of the belly because the warm resistance of this belly so the better remember the more you plug in bearing it drop by this so what i mean. This is the voltage of a battery. Because why that when you plug in the battery and introduced by this means.
It was consumed by the. Debt so the potential difference for this case is 03. Of the battery equal currency currency is going to be the same throughout the.
Cycle which this one which is 05. 85 times. Internal resistance to the beta okay so now lets get into.
The value so i divided by 0585 divided by 085585 using. This console so ill take. 03 divided by divided by 0585 and finally our internal resistance of a bearing equal.
052. What oh because the unit of resistance is bomb. So now.
Its just easy like this minute to many times with this belly. These internal resists on this padding. Okay now lets go to equation number.
Two question. Number two is easy man you know like i said i feel like i watch some time here because these equations okay okay. Now we go this question here now what you dont want to say uh that what here is connected to to our voltage line.
Oh. How much heat. Also this is the one hits energy is easy man so from the front.
We always say uh power or power equal to energy. Over time energy over time g energy. Over time power.
So i can write today power equal to energy for time. But for this case. Im looking for the heat energy means.
Im looking for this heat image. So how many energy. I can cross multiplication.
So i can just say p equal to energy over time so im looking for energy for this case. So just cross multiplication. So one cross energy times.
One equal to energy power. Times t is power times t. So now do we have a power.
Oh yes. This is the power right here okay. So one thousand one two times time yes we got time to say.
Its two hours so these two hours always when you read the time the time got up in seconds. Okay. So this is going to be true okay.
How two hours you have to change hour to second so check my hour chain two minutes so if its two hours if i change two minutes. Im gonna multiply by sixty fifths six days oh we dont know one minute it has to be second. So to say from minutes to second you have to multiply again for six and again by 16 okay so for that case now if you multiply this right you pretty calculate this gonna give you ten eight one two three four five okay one two three four five okay so this one here uh uh.
This is joule remember okay so we can change to mega joule. Okay. So change omega just makes you divide by uh divide.
All these i can say this 10. 8. 1.
2. 3. 4.
5. Divided by okay. Two three one.
Two three another three one two three and this is a mega joke. You know what im saying. So now.
We say one two three four five six one two three four five six. So its going to give us 10 point eight. What mega zhu.
You know what im. Saying you know so were going to have a 108 negative. Oh so energy or if you want to approximate so answer equal to 108 mega joule.
But if your approximate is gonna be eleven or maybe two it just wastes your time you do this question. And its easy like that man thanks a lot you know what im saying look man.
I believe in learning from how to do things if its time make sure you subscribe and you know you can just go and do donation to our patreon page. I have a patreon. I have a gofundme you know what im saying.
I have all the means of donation because to make this project going you know any type of donation. The little that you think is too small for you it could make a lot of change and thanks a lot for all your time. You know subscribe dont forget share this video circulate to a lot of people you know because the meaning of this project is program.
Its half as many as we can okay. Its not only for one person two because you might think. Its not helpful for you.
But for somebody next out there. It could be very very helpful so thanks a lot man. And you know any donation that you did to me it means so much i appreciate man it means a lot go to our patreon page go to our uh gofundme.
Because we need to have a you know a lot of things we need to put them together like camera. You know and a lot of equipment so that we can improve on you know a lot of a lot of aspects of these projects. You know thanks a lot man.
I appreciate and i love you peace music. You know this is one of my students of knowledge you know she wanted to juice herself whats your name could you please introduce yourself music everywhere right so. This is my other son.
His name. Whats your name. Matthew matthew yeah.
Hes great man. So. His aim is to score decision right so you promise i want you to scroll through this time.
You know what you may be. Joshua joshua. How much you promised me to call.
This hand. Distinction. Just everywhere.
Music. Thanks. So much music music applause.
Oh music no because. Its really. Good.
They actually has helped a lot first. I read it first year for maths. It was my own fault.
But also i didnt know a lot of the work and ami said lots of hard questions and its its demotivating sometimes to do the harder stuff you like just want to get done. But its the hard stuff. That makes you realize.
The easy. Stuff. Is easy.
Music. Oh music. Oh.
Music. Music. Yes.
Applause. Yes. Music music.
Sing. With me. Music.
