A conductor of capacity 20 mF is charged to 1000V. The potential energy of the conductor wi(a) 20 x 104 J(c) 20 × 103 Jbe(b) 104 j(d) 10

Answer»

Energy stored in a capacitor = cV²/2

Given

Capacitance = 20 mF = 20 x 10^3

Voltage V = 1000 v

Hence

energy = cV²/2

= 20 x 10^-3 x 1000^2 / 2

= 10^4 J

= 10 KJ

Hence the energy stored in the conductor will be 10 kilojoules.

(b) is correct option
