Electric Permittivity

019 - Electric Permittivity
In this video Paul Andersen explains how electric permittivity of a material resists the formation of electric fields. Capacitors store energy be preventing the formation of electric fields in dielectric material. The electric permittivity of free space is constant and increases in insulators.

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!

[@offchance789]

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

[@4pharaoh]

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?

[@narendrachintala7998]

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

[@rahuldeendyal5946]

[@MrGdsuta]

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?

[@ringobd908]

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

[@leoclarkin5944]

very helpful

[@devendrakumar7124]

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

[@motobacktoconstitution4138]

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

[@nikkuupadhyay5639]

excellent sir you are a genius

[@jeremyweaver5814]

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.

[@programmer7592]

Thank you sir

[@Phil659]

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

[@gehadyasser1001]

[@yusufahassan5833]

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

[@kiransteward5387]

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 ?

[@ramtejaguthikonda6333]

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?

[@dannybeckett01]

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!!

[@sheminjose5481]

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

[@user-ee8hx1xq9i]

4:02 Could anyone explain why does the electric permittivity increase resistance while it also increases the capacitance? I didn't take ap physics 2 but have to know this concept for the subject test

[@adityashah5597]

Not so sure either but, I think without any dielectic medium the charges accumulated at the two plates would create Electric field which would make them to loose energy And adding those mediums with "resistance" would allow some of those fields to be cancelled i.e., leass field and thus more chage would be stored in a capacitor

[@pedrogaleano6722]

The thing is that capacitance is equal to Q/V, where V is the voltage (difference of potential). Meanwhile, if the electric field is constant (like in this case) V=E*d, where d is the gap between the plates. Because the dielectric increases resistance, it reduces the electric field and so E*d becomes smaller, so V becomes smaller and the quotient Q/V increases. Hence, the capacitance increases.

[@laibashahh4808]

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

[@CosmicEpiphany]

It's amazing kids are learning this in high school now. I didn't even have the option to take classes of of this nature when I was in high school 10 years ago.

[@elvarnswd]

Well, don't bother about the pass. If you have a passion in physics, it's never too late to start to indulge into it now. Go for it :-)

[@surbhisoni4282]

Charge is collected on plate or between plate

[@DE-vx6xr]

great!:)

[@mjayy_]

Is dielectric constant reciprocal of permittivity?

[@pjshinelikeastar8229]

Yes :)

[@mayureshnighot8622]

Grt videos 👍👍

[@anirbanmaiti817]

Are electric permittivity and dielectric constant same thing?

[@triplebig]

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.

[@dr.krishnamurthyramanujam4128]

Awesome
