What should be the capacitance of a capacitor capable of storing 1j of energy when potential difference of 100V is applied between the plates?

Explanation

U = 1 J
V = 100 V
Capacitance = C = ?
`U =1/2 CV^(2)`
`C = (2U)/V^(2) =(2 xx 1)/(100)^(2)`
`=2 xx 10^(-4) F`
`=200 xx 10^(-6) F`
`C = 200 muF`
