Answer :
Formula/Consepts Used:
Energy stored by capacitor:
For a capacitor of capacitance C , with charge Q, and potential difference V across it, the energy stored is given by:
Charging a capacitor:
A capacitor of capacitance C is connected in series with a resistor of resistance R, a switch, and battery of emf ϵ . It is uncharged at first. The switch is closed at t = 0, then at time any time t the charge stored on the capacitor is given by
Energy stored in the capacitor is
