Physics 12.4.1a - Electric Potential and Potential Difference

What kind of software is he using??

[JaneFishhouse]

Really enjoy your explanations, simple and straight to the point. You are a great teacher.

I don't understand one thing, can you tell how exactly in reality charges are 'moved' apart from each other for greater PE/Voltage? I guess you can't really take an electron and move it away from quantity of protons with a finger...

I'm very eager to know this.

[derekowens]

@JaneFishhouse  Thanks, and that's a great question. In a netshell: electrons can be moved by inducing a current, which is done by physically moving the wire across a magnetic field. This involve physical work, and the result is current flow. You could also imagine this: instead of moving the electrons, instead change the field around them so that they are then at a point of higher PE.

WOW!

[nrazdan8]

YOU ARE AWESOME. I'm studying for the MCATs and I dreaded the Physics section, but you are making me feel much more confident. You are organized, clear, interesting, and an excellent explainer. I really appreciate your efforts.

[WTFdomination]

You sound like George Bush but more canadian...

[TheDevilvivek]

i learn electricity when i was in class 7th

[godzilla5500]

@TheDevilvivek You should've perfected your grammatical abilities instead...:(

[RayTanZL]

Your 8 minutes is better than my teacher's 8 hour's explanation ...

[MrAruneshshan]

intelligently explained!!

[XjhonnieX]

nice vid men regards from spain

What is the diference between work and energy in physics?

[derekowens]

@ncthis Mathematically, they are the same. Energy is often defined as "the ability to do work".  Work done and energy expended are typically the same thing.

[godzilla5500]

@derekowens When 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.

[derekowens]

@godzilla5500 Electricity is definitely part of the study of Physics, which fits more broadly in the Physical Sciences. In my mind, one of the key aspects of current electricity as opposed to static, is that all the electric devices we use run on current electricity. Being able to harness and control the electric current has changed the world in a profound way. If you have to distill it down to one equation, focus on Ohm's Law.

i come home after physics class and i watch your videos--- it's like a better way to take the course! you've taught me everything, keep it up please!

[iffarle]

very usefull.tks!

[leang3000]

THANK YOU THANK YOU x 10^99999

just appreciate you making a video to the public so much

i cannot thank you enough!!

:)))))))

[SORA3412]

Thank you!! this is really helpful...!!!!

[CopperStarcraft]

You're the best, Derek!

[Valkayre]

nice! I like the way you explain and draw the examples..

many thanks for the videos!!!!

[happy321hh]

wow ur better than all my teachers combined

[KathyEngineerGV]

your videos helped me understand this material so well! My professor just assumes everything is obvious to us, so he doesn't explain stuff too much.

Hopefully I do ok on my exam tomorrow!

[viayal]

You can be a little bit fast

[PepperShock77]

@viayal pause the video then....

[starlightsl]

you are my god. <3

[exce11er]

Good video even though it sounds like you took a massive crap at 1:30

[jtlangel]

Where were you when I was in high school? =(.. very educational videos

[koolfool132]

@undergroundspark  amen

[flanders]

you sir.. are awesome

[GigaFro]

Grunting sounds.... kinda scare me.

[krazygoluver]

Wow, this is awesome! The explanation is so clear and your examples make it so easy to understand. Love the drawings too! Thank you so much! :)

[terentulla]

thanks....

[amaznflipasian1]

Thank you muchos!!!!

[Yohannesiscool]

you should be my teacher. simply excellent in drawing and explanation.

[monroetsd]

i love the grunting sound effects lol

[TheCriticalGouge]

Nice explaination

[imaan7]

you are just awesome

that was sooo helpful

thanks

[MistrEgg]

you are PRO at drawing on that thing.

[anmool9]

awesome!

[djdeviate99]

great demonstration!!

[devashish18yadav]

nice

[pastelhorizon]

Your teaching is amazing.

[wongngmui]

thx

[chinadimsum]

good ,clear ,thx

[adkalmos1]

thanks bro
