Question

A capacitor of capacitance 50μF is charged with 10 V. The energy is

A) 2.5 x 10^-4 J

B) 2.5 x 10^-3 J

C) 5 x 10^-2 J

D) 1.2 x 10^-8 J

Answer 1

The correct option is (B) 2.5 x 10^-3 J

It is given that, Capacitance of the capacitor, C=50 μF = 50 x 10^-6 F

Voltage, V = 10 V

It is assumed to find the energy stored in the capacitor. It is given by the below formula as:
