one of the finest explanations i ever had on you tube, thanks a lot.

Wow! such an easy way to explain what permittivity is! I couldn't find an easy explanation anywhere! As soon as you showed the flow chart with the word 'resistance'. It all made sense! Thanks!

going back and re-reading the wiki entry on relative permittivity feels intuitive now.

Mr. Anderson, I love you. You're a lifesaver!

Practical and impeccable description. The simulation is pretty handful as well. Thanks for this video.

Your videos always rock mr. Anderson!

No book could do this to me. Stunningly simple and yet crisp to the point. Thanks a ton Mr Bozeman

Oml Mr. Anderson I've been watching all your physics, chemistry and biology videos and honestly yr vids r the most helpful and best so far... thank you so much for helping... love from India

Brief and well explained. Thank you!

this is by far the best video i have ever seen thank you so much

Thank you so much for this video. you clear my all doubts in a very easy manner. The way you represent the opposite electric field of di electric is much more tha Awesome!! Thank you again

That was helpful. Thank you sir. I've read a lot of electric smartass wannabe's articles that explained permittivity and none of them can explain it in basic form. Thanks a lot

These videos rock.

An awesome video that saves my life. Thank you!

I have seen a lot of science videos but this one is really creative , making a capacitor from foil and plastic ingenious !

Very nice and wonderful video. It very informative and concise to understand the concept very clearly. Thanks a lot. Please upload more videos like this.

This is brilliant. Thank you!

Thank you Super concise, super helpful 💥 def subscribed Man I hope the rest of your videos are like this one 🤙🤙🤙

sir,you are lifesaver.

Your channel is awesome!!

Very well explained. Bravo. Keep up the good work👍🎉

Thank u for explaining. This was really helpful

thanks for the video. I was for searching the same question for a while now..... it helped a lot!!!!

EXCELLENT VIDEO!!! thank you!!

Such a great explanation sir.... I found this lecture really helpful... I Love watching your lectures....

Mr. Anderson much love for you. from South Africa

animations are always helpful

That was really useful, Thank you so much

Very good explanation.

wow, so clear! thank you!

omg this is the best lesson ever, I hope they teach us like this in school

Hey..u r a genius..the concept has got ingrained in my mind now..thnx a lot 👏👏👏👏😝

That's great. Thank you so much

Nice work

Amazing! Thank you very much.

Nice I really needed that :)

that was awsome thank you!

Wow best explanation ever . Thank you very much sir

Thank you, good job

just owsome.. plz make videos on susceptibility, magnetic induction etc

Very Helpful... Thank U

super helpful!

Thank u so much! I learned a lot

Very helpful and simple

Thank you

It was helpful, I am subscribed

Sir, you become my physics guru(teacher) . Love from India.

Awesome bro

thanks.....great video

Thank you!!

The explanation was superb! Specially that simulation, can anybody tell me the name of that simulation software

Thank you so so much.

very useful information got in a few minutes.

very cool!

Very nice

Thank you for the explanation. Could you please provide the name of the software used for this particular simulation, thank you.

Very helpful 😊

Great. Thank you sir!

Really helpful.

Thanks sir ❤ you are great ❤

The best explanation

Looking at the examples starting around 3:40, what would you expect would happen if you charged the cap with a glass dielectric (@3:52) and then disconnected the power? Now remove the glass, what is the charge on the cap? Take the glass dielectric plate you removed, and place it between the plates of a second uncharged capacitor. Does it charge? What does the result of the second capacitor becoming charged almost to the same value of the first do to your understanding of what was presented in this video? What is really happening?

It was a great lecture

Thank you for saving my life

you teach better than my lecturer, thanks!!!!

LOVE IT .

Very helpful

sir can you help n fundamental charges each of charge q are to be distributed as two point charges separated by a fixed distance , then maximum to minimum force bears a ratio(n is even and greater than 2

awesome vid. quick question - why do the cap plates have to be in close proximity to eachother? why doesn't a capacitor work if the distance between the plates is massive? i'm guessing the further away the plates, the higher the permittivity of the electrical field? or does the permittivity value not work in that way? Cheers!!

If 'permittivity' is a measure of a medium's tendency to RESIST the establishment of an electric field within it, why was it ever called 'permittivity' in the first place which suggests that something is being 'permitted' or allowed to happen? Its no wonder that scientific terminology is so confusing!!

It means how much is being pemitted and how much is being resisted

@CondensedComments

Dave Humphreys This was my first thought too so I sat here and thought about it. I think maybe a couple of reasons and I think of it as a permitivity 'level' or 'raiting' (like wire gauges), rather than 'how well it lets electrons pass (the latter would lead you to believe that higher numbers = better conductivity).' When they discovered permitivity they probably hadn't tested all materials, so they may have said 'let's just imagine 0 is a perfect material that has perfect permitivity and higher numbers would be higher resistance.' Personally I think it should be called reluctance or impedence but maybe those were taken?

I think of it as how much is permitted negatively, as negativity, permit-ivity, and remember that so it’s how much is negatively permitted

which software do you use to show the last slide(capacitance)?

beautiful

very helpful

What kind of software is that it calcurate capacitence by diffarent materual please let me know name please.

Great, but I’ve never heard of Reynolds wrap so I have no idea what it’s made from, aluminium ? tin? Thanks

Thank you Sir...

Very helpful thanks a lotttt

I'm sorry, aren't those two field lines at the outest (top and bottom) edges at 2:15 supposed to bend outward due to electromagnetic interaction?

Grt videos 👍👍

great!:)

what happens to the force between 2 charges when we put any material other than air in between them?

excellent sir you are a genius

Thank you sir

Can you explain why permittivity is effected by frequency in water? Relative permittivity is 80-81 for RF spectrum but 1.77 for visible light spectrum. I can't understand that phenomenon. I thought it was a material constant.

Damn, I wish that my physics prof can explain like this. He often gives us introductory definitions that are in terms of equations, not concepts

Also note permittivity changes with freq, value at dc-10kHz isn't the same as the value at 300MHz. Dielectric constant typically refers to the permittivity in those low freqs/DC

Why are the protons not be shifted as well which would subsequently cancell out the effect the electrons had and therefore not affect the field ?

Awesome

Why is charge increasing after adding dielectric? Actually as dielectric is forming electric field in opposite direction, doesnt electrons of dielectric flow towards positive side of capacitor and decrease the charge?

Charge is collected on plate or between plate

Hope that was helpful? you sir deserve a medal. that's how helpful you were :-D

plz help me out to explain permitivty vs frequncy plot for ferroelectric material.plz

Is dielectric constant reciprocal of permittivity?

If 2 point charges have 'K' 81 in water then what force these charges Will experience in air

good vid

This is probably stupid, but at 4:20 you say that the dielectric creates a 'resistive field' to appose the electric field, but how does that increase the permittivity because then surely the electrons have nothing to be attracted to if there is no overall force there? Because before they would be attracted to one side of the plates, which in turn repels the electrons on the other side. I don't know if that makes sense, I'm only an a level student so I don't think my understanding is quite right? Thanks for any help :)

Jennifer Bartlett exactly my pt!

Are electric permittivity and dielectric constant same thing?

The relative permittitivity is a ratio of the material's permitivitty in relationship to the permittivity of vacuum. That's why vaccum's 1. This also means it has no units! e_r = 1, for vacuum, not 1 F/m.

Thank u sir .

so permittivity is not a energy loss like resistance instead it do help capacitance right ?
