Question

A 700pF capacitor is charged by a 50v battery. How much electrostatic energy is stored by it?

Answer 1

Answer:

$\huge{\sf{\boxed{\boxed{ANSWER}}}}$

Explanation:

The Energy Stored In Capacitor Is:

It is given that :

Charge on a capacitor, C=700\ pF=700* 10-¹²

Potential, V=50V

Energy stored in a capacitor is given by the following relation :

U=½CV²

C is capacitance of a circuit.

V is the potential difference.

U=½700*10-¹²(50)²

U=8.75*10^-7
