Question

A capacitor has a fixed amount of charge on both plates. When a dielectric is slipped

between the plates, how does the capacitance, the potential difference between the plates and the

electric field between the plates change?

(a) The capacitance increases and the potential difference and electric field both decrease.

(b) The capacitance decreases and the potential difference and electric field both decrease.

(c) The capacitance and the potential difference increase and electric field decreases.

(d) The capacitance and the electric field increase while the potential difference decreases.

(e) The capacitance, the potential difference and the electric field all increase.

Explanation / Answer

(b) The capacitance decreases and the potential difference and electric field both decrease.
