Question

A capacitor is connected up to a 12.0 V battery and allowed to charge up. Once the capacitor is fully charged, the battery is removed and a material with a dielectric constant is inserted into the region between the two plates. From the quantities listed below, select all those items that increase.

a)The capacitance of the capacitor

b)The potential difference between the plates

c)The charge on the plates

d)The electric potential energy stored by the capacitor

e)The electric field between the plates None of the above

Explanation / Answer

a) Capacitance increases with dielectric
b) C = Q/V , so V decreases
c) Charge remains constant
d) Electric Potential Energy decreases
e) Electric field decreases ( Due to decrease potential difference)
