22. The current in an inductor is 0.20 A, and the frequency is 750 Hz. If the inductance is 0.080

H, what is the voltage across the inductor?

A. 70 V

B. 75 V

C. 150 V

D. 140 V

B. 75V

Explanation:

The formula for Voltage across and Inductor is given as:

Vr. m. s = Ir. m. s * XL

Where

Ir. m. s : Current across the inductor

XL = 2πFL

In the question we were given values

Ir. m. s = 0.20A

F = 750Hz

L = Inductance = 0.080H

Vr. m. s = 0.20 * (2 * π * 750Hz * 0.080H)

Vr. m. s = 0.20 * 376.99111843

Vr. m. s = 75.389223686volts

Approximately = 75volts

Therefore, the voltage across the inductor is 75 volts.
