Asked Nov 17, 2019

A 15.0 mH inductor is connected across an AC generator that produces a peak voltage of 9.60 V.

a. What is the peak current through the inductor if the emf frequency is 100 Hz?

b. What is the peak current through the inductor if the emf frequency is 100 kHz?


Expert Answer

Step 1

Given values:

Inductance,     L = 15.0 mH = 15.0 x 10-3 H

Peak voltage Vo = 9.60 Hz

Step 2


Frequency, f = 100 Hz

Inductive reactance:
