The capacity of a condenser is 4×10−64 \times 10 ^ { - 6 } farad and its potential is 100 volts . The energy released on discharging it fully will be

A

B

C

0.025 Joule

D

0.05 Joule

Answer

Explanation

Solution

U=12CV2=12×4×10−6×(100)2=0.02JU = \frac { 1 } { 2 } C V ^ { 2 } = \frac { 1 } { 2 } \times 4 \times 10 ^ { - 6 } \times ( 100 ) ^ { 2 } = 0.02 J
