List of top Physics Questions on Capacitors and Capacitance asked in MET

A charged capacitor when filled with a dielectric \(K = 3\) has charge \(Q_0\), voltage \(V_0\) and field \(E_0\). If the dielectric is replaced with another one having \(K = 9\), the new values of charge, voltage and field will be respectively:

When a dielectric slab is introduced between the plates of a capacitor connected to a battery, then:

Work done in increasing capacitor voltage from 5V to 10V is \(W\). Find work from 0V to 5V.

The radius \(R\) of a soap bubble is doubled under isothermal condition. If \(T\) be the surface tension of soap bubble, the work done in doing so is given by

A capacitor of capacitance \( 5\,\mu\mathrm{F} \) is connected as shown in the figure. The internal resistance of the cell is \( 0.5\,\Omega \). The amount of charge on the capacitor plate is

Argon is used

The capacitance of a parallel plate capacitor does not depend on:
