Solved Examples

Question 1: Find out the capacitance of a capacitor whose electric charge is 30C and the potential difference is 14V.

Given that,
Q = 30C,
V = 14V.

Capacitance of a given capacitor is,

C = $\frac{Q}{V}$

C = $\frac{30}{14}$ = 2.14F


Question 2: The capacitance and charge of a capacitor are 1.2F and 50C respectively. Calculate the potential difference.

Given that,
Q = 50C,
C = 1.2F

Potential difference of the given capacitor is,

C = $\frac{Q}{V}$

V = $\frac{Q}{C}$

V = $\frac{50}{1.2}$ = 41.66V
