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.
