Question

A capacitor stores 12.0 j of potential energy when the potential difference between the parallel plates is 9.0 v. Find the capacitance of the capacitor.

Answer 1

Capacitance of the capacitor is c= 0.29 F

Step-by-step explanation:

Energy the capacitor store related in the equation

`E= 12`Joules

`v= 9`volts

`E=(1)/(2) *C*V^(2)\\ C=(E*2)/(V^(2) ) \\ C=(12 J*2)/(9 volts^(2) ) \\`

`C= (24 J)/(81) = 0.296 \\C=0.296`F

The capacitance of the capacitor for a voltage of 9 V
