Question

A condenser of capacity 50 microfarad is charged to 10 volt energy is equal to

Answer 1

GIVEN:C=50x10^-6f,V=10v
Capacitance of the capacitor C=q/V
50x10^-6=q/10
q=5x10^-4C
therefore, Energy (E) =Vq
E=10x5x10^-4=5x10^-3j

Answer 2

The volt energy is equal to 2.5 × 10³J

Capacity of the condenser = 50 microfarad (GIven)

Energy of the capacitor = 10V (GIven)

Capacity is defined as having the capacitance of One Farad when a One Coulomb charge is deposited on the plates by a voltage of One Volt.

Capacitance of the capacitor C = q/V

U = 1/2CV²

= 1/2 × 50 × 10−6 × (10)²

= 2.5 × 10³

Thus, the volt energy is equal to 2.5 × 10³J
