What happens to the magnitude of the charge on each plate of a capacitor if the potential difference between the conductors is doubled?

The magnitude of charge on the each plate of the a capacitor will become two times larger.

Explanation:

The capacitor is a device that stores electrical energy and gives back the electrical energy to the circuit when needed ie it charges and discharges the electric charge stored in it.

The charges are of two types positive and negative. The charges on the conducting plates of a capacitor are equal in magnitude but opposite in charges.

The mathematical formula to calculate charge on the capacitor is

Q = CV,

Where Q is the initial charge,

C is the initial capacitance of the capacitor,

V is the initial potential difference

If the potential across the conductors is doubled the V = 2 V,

Q = C2V

ie the magnitude of the charge is doubled.
