The plates of a parallel plate capacitor...

The plates of a parallel plate capacitor are not exactly parallel. The surface charge density is therefore,

A

higher at the closer end

B

the surface charge density will not be uniform

C

each plate will have the same potential at each point.

D

the electric field is smallest where the plates are closest.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C

a., b.,c.
Being a conducotr, each plate has the same potential at each point. But because `E=-(DeltaV//Deltax)`, hence `E` is highest where the plates are closed to each other. Hence, surface charge density is also higher at the cloer end.
