Question

A 165 µF capacitor is used in conjunction with a motor. How much energy is stored in it when 119 V is applied?

a) 1.95 J
b) 3.28 J
c) 20,835 J
d) 24,717 J

Answer 1

The energy stored in the capacitor is 3.28 J.

Step-by-step explanation:

To calculate the energy stored in a capacitor, you can use the formula: Energy = 0.5 * (Capacitance * Voltage^2)

Given that the capacitance is 165 µF and the voltage is 119 V, we can substitute these values into the formula:

Energy = 0.5 * (165 * 10^-6 * 119^2) = 3.28 J

Therefore, the energy stored in the capacitor is 3.28 J.
