Polarization of Dielectric || 12th Class Physics Chapter 12

Dielectric polarization occurs when a dipole moment is formed in an insulating material because of an externally applied electric field. When a current interacts with a dielectric (insulating) material, the dielectric material will respond with a shift in charge distribution with the positive charges aligning with the electric field and the negative charges aligning against it. By taking advantage of this response, important circuit elements such as capacitors can be made.

Dielectric polarization is the term given to describe the behavior of a material when an external electric field is applied on it. A simple picture can be made using a capacitor as an example. Figure 1 shows an example of a dielectric material in between two conducting parallel plates. The charges in the material will have a response to the electric field caused by the plates.

Awesome, splendid, sumptuous and gorgeous teaching of method...

[m.younism.younis]

In the absence of dielectric the energy stored in a capacitor decrease or increase?and capacitance increase or decrease???

[laibabutt]

Thank u so much sir g
Your lectures are very helpful

[jaiparkashkuhar]

Sir thank you for this amazing lecture. Your teaching is🥳🥳🥳. I search a lot of videos for this topic but no one can not explain like you.
Please aasia super concept clearing videos banata rahia.🙂😀😃

What is difference between insulator and dielectric if dielectric is same as insulator then why do we call it dielectric and not simply insulator ???

[IfraMohsin-tyqw]

The concept was clear at the end.Thankyouu Sir!

[TaekookHusna]

Assalam o alikum sir can you upload the lecture of combination of capacitors plz😢😢❤

[MuhammadUsman-uwvg]

Aslam-o-Alaikum
Sir kia positive charge slip yani move kr skta hy?

[muhammadimranasghar]

mashaAllah Sir kmal ka lecture deya❤❤❤ thanks a lot sir❤

[splendidworld]

Induced electric field kysa produce hogi polarization k bad plz tell me sir

[raheelgujjar]

Sir Electric polarization ka topic Explain kar day

[abdulrehmanbaig]

Sir agr hum already polar kese cheis ko rakhy too i-e H2O NH3 HCL

[mahidali]

There is a huge difference bw dielectric and insolater

[biologywithfaisalkhan]

Great effort sir allah apko kush rakhe ❣️ sir ma apke lecture 11th class se sun rha hun aur apki waja se mere bht ziada concept clear hue han apki waja se mere inter ma ache number aye han aur physics ma itna interest hua tha ke mane university ma bhi bs physics select kia ha sir plz first semester mechanics ka concept de
