Electric Fields

[@Bawnkeeh]

You saved my semester, sir. I'm in a university and the professor isn't even close to being as enthusiastic and clear as you are. I understand concepts from all your videos. Thank you so much.

[@brightstorm]

[@jinfobaby611]

Honestly one of the best physics instructors on the planet. He really knows how to make complicated concepts seem so simple. Thanks a lot

[@cipfalco]

this guy is the most entertaining teacher, I wish my children would have a teacher like him.

[@ballisticpancake1369]

"It's Not Schizophrenic!!" I lol'd. Love the energy and attitude in your videos man.

[@Aceprocta]

Lol this guy acts like a maniac but makes a lot of sense

[@brightstorm]

Thanks for watching our video.

[@Aceprocta]

No thank you. This helps me understand which books sometimes fail to do

[@swadand]

9 years and it's still helping me.

[@Groundeyes]

You're an inspiration man I like that sense of deductive reasoning, strength and clarity. Thank you you've left me motivated.

[@taladiv3415]

Excellent teacher! I especially respect his effort to be grammatically correct with the word "symmetric" and not the common error "symmetrical". 3:29

[@joshsu935]

I love this guy's energy in teaching physics! Thank you for making this video and helping me!

[@lovelyfrenzy1]

2:32 light bulb moment! I understand the test charge concept now! Thank you!

[@Ccat398]

Your videos are so helpful !!! Thanks for uploading !!

[@DeeNeeBug]

This guy is so good! I'm actually understanding this stuff and I'm just an ordinary, everyday person. The one I like best in this series is the Blackbody Radiation. Who would've thunk it!?!

[@theginjaninja1995155]

thank god a decent teacher on this other than the third level lectures which explains everything in more detail but these help a lot !!

[@elzarqua]

this guy is soo good, my little brother never took physics in his life and yet he understood this when i was watching it!!!

[@legendkiller376]

you make things so easy to understand!

[@itsher9199]

your energy

[@masonwalker6925]

I really enjoy watching your videos. Keep up the great work!

[@KristofferEngstrom]

fantastic teacher xD Easy to understand and entertaining at the same time.

[@orponTech]

Absolutely learn-able

[@TeresaDeJesus1998]

i love watching your videos, they always help me refresh before i take my test. . . and you make it seem so simple

[@G00n3r4Life]

Very good video, plain and simple. Just a theoretical question what would be the case in the final example if there were two negative charges and one positive?

[@heavymetaldeath4life]

Good question. I'm not qualified to answer it. My physicist friends recommend Richard Feynman's "QED: A Strange Theory of Light and Matter", though I haven't read it myself. My understanding is that the photon IS the oscillating EM field.

[@snoobeagle]

Great lecture! It's said that a varying electric field can generate a magnetic field, and that a varying magnetic field can generate an electric field....but intuitively, and as suggested by this lecture, only a charged particle seems to have an electric field. There are no charged particles in a magnetic field (esp. in vacuum of space), so how does a magnetic field generate an electric field?

[@SugerNoor1996]

This teacher is awesome."Alright" I love his accent.

[@HarpreetSingh-wy8cl]

I really like the way you teach,you are doing a great job rest the students should follow their test books...Keep it up .....God Bless you friend!

[@media4401]

This dude is an example of why professors are better than High School teachers, it's all about the passion.

[@steveg12345678910]

i love his enthusiasm

[@russelmillena4827]

That line "I wander why?" tho hahahaha

[@ayursheehaldar8195]

Awesome explanation sir.!!..You make physics really enjoyable and easier to understand .😎

[@rhishikeshdongre7553]

Awesome,everything made sense and its got deep in my brain, Thank u sooooooo much sir and I was not bored for a second so ur really a great teacher.

[@나비방탄소년단]

3:34 I couldn't stop laughing and my mum thought I wasn't doing homework for a moment. ''REPULSIVE!''. Why is he so angry at me. ;_;

[@ibenrejeb4463]

OMG I WOULD HAVE FAILED IF I DIDNT FIND YOUR VIDEOS!!!!!!! THANK U SOOOOOO MUCH

[@cameydikshan9545]

sir,.i wonder dat teachers dat really can teach exists in dis world ,whoever u are,...i wanna just jump n give u a big hug,..coz u did da job,.dat my sucking fysics sir dint,...plzz plzzz upload da video for elecric flux,.electric dipole n all stuff i'll b very thankful 2 u,...!!! n keep going on,...ur awesome !! :D

[@tpain5974]

You're a legend mate!

[@NeMucn]

Holy shit. This guy is a legend

[@viperz301]

iv got a question , 09.03 , since E is created by' +' , the electric field is going outward , does this mean that the electric field will continue to go outwards , and only be ended if a negative charge is placed ?

[@the_blue_dot]

i like his way of teaching very much.

[@Imafungi123]

QED is pretty much the significance of the frequency of oscillation at which charged particle moves in relation to another creating an amplitude and wavelength of disturbance in the constantly discrete EM field? So does a photon exist because it travels through the EM field of all ever local EM fields? There is a constant EM field which when disrupted by an accelerated charged particle,causes a flux in the EM field,and as it locally stabilizes, it passes on the disruption?

[@minniestrindin5574]

This guy has Adrian Pimento energy and I'm loving it

[@nicholasmorton5505]

Lol who gave a thumbs down, this guy is on point. Teaches better than my professor at college, for which I apparently pay way to much money for.

[@someone20ify]

all the male brightstorm2 teachers are funny and great!!

[@DioD3]

Super helpful video.

[@lovelyfrenzy1]

So, sir, I have one random question. Great job so far- I am only half way into the video but how does one have a test charge? The problem I have with physics is that everything discussed is so "hypothetical" in my mind.

[@paintballa2020]

Its amazing to me how I can pay 20000 dollars a year in tuition just to sit in lecture and struggle, go home, and watch a youtube video that clears everything up in 10 minutes. Thanks

[@Morfij]

great teaching style!

[@rajeshkuvera4983]

it is of great help to me.......thanks brightstorm

[@zzzzbisonxzzzz]

7:00 light bulb moment. thank you!

[@sayyidrajab6657]

This guy is awesome!!

[@Visy23TheElf]

I have the problem with most video lessons being to dull, with the person giving the knowledge sounding like they are talking to a child. meanwhile you have the energy of a honey bee on steroids after finding a flower while dancing to tell the hive about it! what Im trying to say is: this video is great and well presented

[@alexbloodpath4997]

really you helped me alot dude

[@snnasser3563]

You're a really great teacher ❤️

[@Simis999]

IT'S NOT SCHIZOPHRENIC :D

[@RootyRooTheKangaroo]

What would i do with out the website? Amazing work, you make it so clear compared to my nonsense physics teacher!

[@iJuicyMamacita]

I love when I pause, he has so funny face expressions!

[@Imafungi123]

K thanks. That has to do with quark color model and gluons and spin states?

[@Snipersounds]

Great teacher!

[@smartbro678]

This guy is awesome

[@puranpagol]

awesome explanation boss....wanna know about how radio waves work

[@Mohamed-zo6so]

+Puran Pagol radio waves are electromagnetic waves a combination of electric and magnetic waves

[@Imafungi123]

What is physically different about a positive charge then a negative charge (why does charge exist, how was it created?)? What physically is going on, when a positive charge is attracted to a negative charge? How does the negative charge create external suction forces (field) to attract the positive charge?

[@Jipoze]

I find it hard to look away from the eyes , they're intense .

[@jackpie101]

AMAZING

[@vorman4]

@nanone1994 no you don't have to draw 4 he drew them so we can see how strong is the electric field compared to the one with 8 you can draw a million if you want

[@HoldzItDown]

please come teach physics at ucsd

[@joncutrim1161]

what about minus minus what woud happen i know that it repells too, but you said they atrack energy while positive spreads

[@Paradox3627505]

Is it safe to assume that any electrically neutral object (i.e. a cup, an ink pen, etc.) a.) does not produce an electric field and b.) is not affected when an electric field is applied to it?

[@carultch]

Globally, yes. Locally, no. Every force you experience at the macroscopic level, other than gravity, is ultimately electromagnetism in some form or another. The reason the cup doesn't fall through the table, is that there is a localized electrostatic repulsion at the point of contact. There's also polarization that can make neutral objects attract charged objects, because of the charge signs being distributed to opposite sides of the object, such that the near charges are opposite and the far charges are same. On net, this adds up to an attractive force.

[@badgoed0]

All teachers should be like him

[@gihan1993]

"this guy here owwwwww, like that" 6:59 ..haha..this guys is funny :D

[@weibao8165]

most helpful video i ever seen

[@bios546]

Really helpful... and a really enthusiastic vid. :D O nd... huge eyes... not like the anime ones... but... kinda immense!... a good thing. It would look better with a concept called sharingan.

[@andrjsjan4231]

5:40 well it can go up as a result of the sum of the force vectors right??

[@poanli109]

So helpful

[@youngin8181]

goddamn this guy is actually a straight up G

[@heavymetaldeath4life]

No, that's Quantum Chromodynamics (QCD). QED is based on electromagnetism, whereas QCD is based on the strong nuclear force.

[@heavymetaldeath4life]

To understand what's really happening when charged particles, whether positive and negative, interact, you need to learn Quantum Electrodynamics. Google it, but don't rely too much on websites. Get a decent physics textbook and start reading.

[@cabezon12311]

so then....back to my toaster question. is the electric field what happens once I push my toaster button then stops before I release the button?

[@iMaria324]

great vid though! Thanks

[@cabezon12311]

lets say I push down on my toaster button to start cooking some waffles. where would the electrical exist or take place while my waffles cook?

[@flaviusone]

this guy is so amazing

[@TheCphase]

Wow, our teacher never really explained the whole thing with 4 lines and 8, etc. makes a lot of sense!

[@stevenan93]

i straight up lost it at 5:27. spaghetti everywhere

[@peacebewu]

@ 10:46 ..on diagrams what about the interaction between to negative charges?

[@ambarishshukla2710]

beeessttteessttttttttt...... explanation 👌👌👌👌👌👌

[@MemoNenoBemo]

thxxx A lot!

[@jyothiks1380]

thank you sir

[@AhmedSayed-ki3fm]

ya saved my final exam ,thank you too much

[@sachinshah4594]

A little error there...I think the electric field lines are created by +ve and destroyed by -ve,not the electric field.

[@nanone1994]

I have a question and some body please clear it for me : do we have to draw 4 electric field's lines per one charge? i mean is it a rule? because i notice in my textbook they draw 4 lines per one charge and when there was an example similar to the third one u gave of two ++ charges they doubled it so its 8 ! but is there a constant rule cuz i noticed they're using even numbers in giving examples but is it possible we use odd numbers to draw the fields? please answer, I'm confused :S !

[@hamtaro13579]

dang~~ he explains way better than the physic teacher i have now~~~~=.=

[@raykay126]

How do we know there are electric field lines? why aren't they just spheres of energy? Or do we know they a spheres of energy and the lines are used to show how powerful the charge is?

[@carultch]

The lines don't really exist. They are just a visual representation of the patterns in the fields we can measure

[@donnawouters]

I wonder what would happen when forcing the lines to cross. Maybe it'd generate a black hole.The physical equivalent of dividing by zero

[@tejaswinipatil3968]

hey do you have something on permittivity? I m reading stuff given on the internet but found very difficult to understand....

[@carultch]

Permittivity is just the k-constant restated from a preferred form in Coluomb's law to the form preferred for Gauss's law. In Coluomb's law, the k-constant is out in front, and is equal to 1/(4*pi*epsilon0). The epsilon0 value is the permittivity.

[@v1tusphoenix]

"the direction of the force on the positive charge" can someone explain this, please. does it mean that if the charge is positive and is moving to the right, the vector arrow would point to the right??? A2 physics is confusing this guy helps a lot. But, unfortunately, English as a second language means that i'm a bit slow to catch what he means. Helps please, ^_^

[@Zer0kill001]

He is looking into my soul

[@NicholasChioy]

this guy's eyes force you to pay attention

[@donnawouters]

Am I the only one still expecting "Science, bitch" instead of "Science brightstorm" in the intro.

[@therealjordiano]

dat revelation at the end :O

[@paulduggar5888]

thanks crazy physics professor dr osborne

[@Raghy07]

Alright!

[@ksvsk]

nice teacher

[@rockerogranuja9428]

Everything is clear now
