Question

C, V, U and Q are capacitance, potential difference, energy stored and charge of a parallel plate capacitor respectively. The quantities that, increase when a dielectric slab is introduced between the plates without disconnecting the battery are (A) V and C (B) V and U (C) U and Q (D) V and Q

Tardigrade Admin · Accepted Answer

When battery remains connected C=KC Q=KQ V=V E=E U=KU Hence, Q and U increase.

Q. $C, V, U$ and $Q$ are capacitance, potential difference, energy stored and charge of a parallel plate capacitor respectively. The quantities that, increase when a dielectric slab is introduced between the plates without disconnecting the battery are

V and C

V and U

U and Q

V and Q

U but not Q

When battery remains connected
$C = K C$ $Q = K Q$ $V = V$ $E = E$ $U = K U$
Hence, Q and U increase.
