Question

A 12pF capacitor is connected to a 50 V battery How much electrical energy is stored in capacitor​

Answer 1

Answer:

Solution

Capacitor of the capacitance , C=12 pF =12×10−12F

potential difference, V=50 V

Electrostatic energy stored in the capacitor is given by the relation,

E=12CV2

=12×12×10−12×(50)2

=1.5×10−8J

Therefore, the electrostatic energy stored in the capacitor is 1.5×10−8J
