Question

A parallel plate capacitor C has a charge Q. The actual charges on the plates are a)Q,Q b)Q/2,Q/2 c)Q,-Q d)Q/2,-Q/2​

Answer 1

Answer:

:- (c) Q -Q

Explanation:

A parallel plate capacitor Has a charge Q.The actual charges on the plates are

:- (c) Q -Q

Answer 2

The correct answer to the above question is (c), which is when a parallel plate capacitor C has a charge Q. The actual charges on the plates are Q, -Q.

• When a parallel plate capacitor of capacitor C is connected across a battery of potential difference V, then the charge acquired by the plate will be equal to Q = CV.
• In an ideal capacitor, the entire charge is accumulated on both plates.
• This charge will be equally distributed on both plates but will be of opposite charge, that is equal and opposite.
• Therefore, the charge will be +Q and -Q.
• Q is the charge in Coulombs on each plate.
• The positive plate has a charge +Q, and the negative plate has a charge -Q
