Answer:
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.
