Question

How does charge store in capacitor?

Answer 1

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.

Answer 2

WHEN ELECTRICITY GO IN THEN ELECTRIC CHARGES IS BUILD UP BY THE PLATES.

ONE GET + CHARGE
ANOTHER - CHARGE
