potential difference

[iamcool1323]

my 1 hour physics lesson in 10 minutes :P

[RobFS1]

The transitions in this video remind me of Super Mario 64.

[bluemaki1]

it is old but very useful ! thanks a lot

[DipSet85]

is the heat element described in the circuit reffering to thermal voltage, VT? which is 25mV at 300K?

[30086533]

Hi there, are there a series of these videos - if so, what are they called and where could i get them? Thanks!

[UnexptedB]

It ages well.

[66vivek]

at 7:50 ,he says that if DA and AB are good conductors of electricity, the potential difference between the two points DA and AB is 0. --- i didnt understand this part.

can anyone please help me out????

[Anim8edDeath]

@66vivek If they are good conductors, the potential energy lost to work is essentially zero, so potential= 0J / 1C = 0v

[Joostvantiel]

@66vivek Imagine the skiers. When they are at the bottom of the slope, they have to move to the lift again. Because they still have some velocity and the snow is almost frictionless, the skier does not lose energy while travelling that distance. The same goes for electrons in a good conductor. There is no friction for the electrons, so they don't lose any energy, so there is no difference in potential energy between point A and B (or C and D)

[loqkLoqkson]

this is terribly convoluted and, in several cases, wrong or misleading.

for example, in a battery, the coulombs do not pass through the battery, gain energy and keep going, that's what happened in a generator. a battery has a bunch of electrons in one chemical that are pulled to another chemical through the wire.

there is a great video that uses water to demonstrate electricity, but i haven't found it here. if i find it, i'll see if i can post it

[Joostvantiel]

@loqkLoqkson Don't you think coulombs passing through a battery is sufficient for this audience?

[benjileek]

@loqkLoqkson Please do sir

[FrizzyFranc]

this is PERFECT.... a GREAT explanation of the concept

[leesang2010]

This video is legendary, i don't understand why school teachers cant explain it this way!!!

[metalmaniac767]

What's with the sound??!

[ultimatebug100]

I hate cliffhangers i was getting so excited. Otherwise awesome video.

[ThatBritBloke]

Not old - Retro

[BazookaSpyder]

These videos were created by TV Ontario years ago. We used them to teach these concepts in class but don't anymore because we can't find the video tape. I just spent an hour the other day trying to track where I could buy them again on DVD and couldn't find anywhere. I wish I had just looked here first!!!!!

[godzilla5500]

@BazookaSpyderWhen referring to current electricity, what particular field study is it under? Also,if you were to give a presentation (like i have to) what particular aspects of current electricity do you think are pivotal to explain? it'll only be like 3 minutes of talking generally about the topic.

[Kaulstoessl]

I just stumbled here after searching the web & spending +3 hours reading physics texts to get a grasp of what the fuck *voltage* really means. This is the first explanation that gave me the feeling that I've got it. Thanks for the upload!!!

[CallMeFirefly]

Oh wow, I was panicking so much that I didn't get it, thanks so much for this :)

[JonnRooney]

professor moriarty himself explaining im honoured

[jonnya42]

@coldarc Electrical resistance is a property of the wire dependent on the type of material, its length, and its cross-sectional area...it isn't gained or lost (there is also a temperature dependency for some materials). Energy is gained and consumed, not resistance. I have no idea what you think you are saying in the last two sentences.

[tehtud2008]

what is the next program???!

[MrSajikhan]

FIRST OF ALL I AM SO THANK FULL TO YOU FOR UPLOADING THIS VIDEO. WOULD YOU PLEASE LET ME KNOW THAT FROM WHERE I CAN GOT THESE TYPES OF VIDEOS.

[peppercorns207]

Just had a synthgasm. Where can I find the sound track?

[trollwarlord3]

excellent is an understatement! :(

[01yaseenshah]

It is Marvelous explanation of  Brilliant phenomenon.

thanks april1515

[rkverma16]

My son use to ask me about the meaning of potential difference and I used to give him a stereotype explanation and he was never satisfied. But this video has made me in his a true teacher.Credit goes to you guys. Thank you.

[Zooter123]

WOW LOVE THIS VIDEO !!! Why can't every textbook I buy explain everything like this video? Everything made sense!! Finally!!!

[wendiwilson13]

great video my husband was trying to explain and he does a good job but this made it a lot easier.

[KKinsane2009]

@2:34

lol.

@3:14

can skiers re-enter earths atomsphere? XD

[rxgvhqkrywq6cxdjoar2]

I'm a 3rd year electrical engineer - this video cleared up more than any textbook ever could. Youtube is changing the way we are educated and will inevitably lead to great things. Never before has it been so cheap and easy to obtain such a high quality education. Thank you!

[strawdog1234567]

You Tube is changing the face of education in the world and because of that the world will change. Never has there beena better resource of supplementary education as that found on You Tube.

[oOAstarOo]

i've never understood PD before this vid Thanks

[ahsan14jan]

Thank You .....awesome video

[CurlyVogel]

THANK YOU *falls to the ground dramatically and cries* I actually get it!! now off to learn more physics!

[rocker9455]

Thanks for this, it really helped me to understand despite the horrific sounds! haha

[Ryan0H]

I love the background music. I want to make some like that someday. Very informative video. I learned something new today.

DOOO000ooo

[jubeininja69]

helpful. i spent hundreds on textbooks yet none of them can explain voltage clearly like this video.

[Vegenad]

Thanks for uploading this. Very instructive!

:)

[SuperTrueGirl]

thanx.....very easy to understand

[EmilyThorpe]

this is brilliant!

[sruhan007]

very good

[jack09811]

very good explanation

[nosorog91]

I understand it

[RuhmaShahzad]

i didnt understood it

[rocker9455]

@RuhmaShahzad

With english like that i'm not suprised!

[RuhmaShahzad]

hey ,look not everyonr belongs to U.S.A or australia and not everyone can speak english fluently, still,i'm sorry about the mistake.anyways it WAS a good video,the problem was we have never been taught that way!

[tnagan]

Funny, but useful!

[Weeeooojr]

lmao, same one I saw in class.

[devashish18yadav]

eccellent video

[TheTomD]

Great, thank you!

[123yuechris123]

Thanks so much, helped alot. :)

[n00448198]

Great explanation, Thank you

[Trackman2007]

Thank you! Amazing explanation. I saw at least 10 other explanation and this is the BEST of those!!

[brilliantfranz]

brilliant !

[Leviathen93]

Hmm... wheres the next one?

[isitthatway]

Where did this video come from and how can we watch all of them in order?

[maker2000]

lol i never new that lol they all come together at once awesome

[RestauranteChines]

honestly, these older videos explain far better than many of modern ones.

[maker2000]

your saying that in older days that they had more info then now

[RestauranteChines]

I dont know about info, but would be natural to have more info in the actual times I presume.

[maker2000]

yah i guess ur ight i was thinking since the world today is more advance we should have more info, than the older days

[tnguy93]

Thanks so much for this video. You've saved me an hour of study!

[ArtFesti]

Hi,

Very interesting videos. I'd like to buy this set of videos. Please, could you tell the Title of this set of Videos and where I can find them.

Thank you for uploading these interesting stuff.

[isitthatway]

Yes me too! Where can you find these videos?

[xsxcxxdanix]

omh i get it now!!

this videos unreal!xD

[aliquidcow]

Thanks, trying to brush up on my electricity knowledge, this video was very 80s but it helped a lot.

[stanke89]

Thanks a lot for this explanation!!! Much easier now.. =)

[GeorgeLovesTiffany]

very 80s

[bmarl0459]

This is an absolutely perfect explanation of potential difference and voltage.
