A parallel plate air capacitor is connected to a battery. Its charge, potential difference, electric field and the stored energy between the plates are Q_0,V_0,E_0" and "U_0 respectively. Keeping the battery connection uncharged, the capacitor is completely filled with a dielectric material. The charge, potential difference, electric field and energy stored become Q,V,E and U respectively. Which of the following is correct? V gt V_0.

Answer»

SOLUTION :Since the capacitor remains CONNECTED to the battery its voltage remins CONSTANT.
HENCE, `V gt V_0` is not CORRECT.
