Question

A capacitor is charged and is not connected to a battery, potential between plates of the capacitor _____ when it is filled with dielectric

Answer 1

Answer:

The capacitance increases as the dielectric constant K>1.

(ii) Potential difference

. As C increases and Q remains the same since the battery is disconnected, the p.d. between the plates decreases.

(iii) Electric field

where V is the p.d. and d the separation between the plates. As V decreases and d remains the same, electric field aldecreases.

(iv) Energy stored in a capacitor

. As Q is constant and C increases, U
