(a) Explain what is meant by the statement: The capacitance of a parallel-plate capacitor is 2\(\mu\)F

(b) State: (i) three factors on which its capacitance depends

(ii) three uses of capacitors.

(c) Derive a formula for the energy W stored in a charged capacitor of capacitance C carrying a charge Q on either plate.,

(d) Two parallel-plate capacitors of capacitances 2\(\mu\)F and 3\(\mu\)F are connected in parallel and the combination is connected to a 50V d.c. source. Draw the circuit diagram of the arrangement and determine the:

(i) charge on either plate of each capacitor

(ii) potential difference across each capacitor

(iii) energy of the combinad capacitors.
