Find the charge stored in the capacitor.

In a charged capacitor, the energy is stored in

A 6 mu F capacitor is connected to an AC source of frequency 100 Hz . Calculate the rms value of voltage if current in the circuit is 1.2 A. Also calculate the average energy stored in the capacitor.

Two capacitors of capacitance C_(1) = 2 muF and C_(2) = 8 mu F are connected in series and the resulting combination is connected across 300 volts. Calculate the charge, potential difference and energy stored in the capacitor separately.

If a 4muF capacitor is charged to 1 kV, then energy stored in the capacitor is

Two capacitors of capacitances C_(1)=2muF and C_(2)=8muF are connected in series and the resulting combination is connected across a 300V battery. Calculate the charge, potential difference and energy stored in the capacitor separately.
