An equipotential surface is a surface ______.

A variable capacitor and an electroscope are connected in parallel to a battery. The reading of the electroscope would be decreased by_______

A  2 μF  capacitor C1  is charged to a voltage 100 V and a 4  μF  capacitor C2  is charged to a voltage 50 V. The capacitors are then connected in parallel. What is the loss of energy due to parallel connection?

If the potential difference between the plates of a capacitor is increased by 0.1%, the energy stored in the capacitor increases by  nearly:

If the diameter of earth is 128 x 10²   km, then its capacitance will be:

If a charge moves in an electrical field:

If the charge on a capacitor is increased by 2 coulomb, the energy stored in it increases by 21%. The original charge on the capacitor (in coulomb) is:

In series combination of capacitors, potential drops across the individual capacitors are equal to_______

A capacitor of capacitance C is fully charged by a 200 V supply. It is then discharged through a small coil of resistance wire embedded in a thermally insulated block of specific heat 2.5 ×10² Jkg⁻¹ K⁻¹  and of mass 0.1 kg. If the temperature of the block rises by 0.4 K, what is the value of C?
