Question

A capacitor of capacitance C carrying charge Q is connected to a source of emf E. Finally, the charge on capacitor would be

Answer 1

The charge on the capacitor will be Q = C E

• A capacitor can be defined as a device that stores electrical energy in an electric field.

• As per the question, the capacitor having capacitance ( C ) is connected to the source of emf ( E ).

• Therefore the potential difference across the capacitor becomes constant. i.e is equal to E.

• Thus, the final charge Q = C E.
