Question 2.10: A 12 pF capacitor is connected to a 50V battery. How much electrostatic energy is stored in the capacitor?
Answer :
Capacitor of the capacitance, C = 12 pF = 12 × 10−12 F
Potential difference, V = 50 V
Electrostatic energy stored in the capacitor is given by the relation,
Therefore, the electrostatic energy stored in the capacitor is
