Question

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

(a) It becomes four times larger.

(b) It becomes two times larger.

(c) It is unchanged.

(d) It becomes one-half as large.

(e) It becomes one-fourth as large.

 

(ii) If the potential difference across a capacitor is doubled, what happens to the energy stored? Choose from the same possibilities as in part (i).
