Question

A 12pF cpacitor is connected to a 50V battery. How much electrostatic energy is stored in the capacitor?

Answer 1

the electrostatic energy stored in the capacitor is 1.5 ×10^-8joule.

Answer 2

Answer:

the electrostatic energy stored in the capacitor is 1.5 x10⁻⁸ J

Explanation:

Capacitance of the Capacitor = 12pF = 12* 10⁻¹² F

Potential Difference (Voltage) = 50V

electrostatic energy is stored in the capacitor = (1/2)CV²

= (1/2) * 12* 10⁻¹² * 50²

= 6 * 10⁻¹² * 2500

= 15000 * 10⁻¹²

= 1.5 * 10⁻⁸

the electrostatic energy stored in the capacitor is 1.5 x10⁻⁸ J
