Question

A 24.0 mH inductor is connected across an AC generator that produces a peak voltage of 10.8 V. Part A What is the peak current through the inductor if the emf frequency is 100 Hz? Express your answer to two significant figures and include the appropriate units. IL= Part B What is the peak current through the inductor if the emf frequency is 100 kHz? Express your answer to two significant figures and include the appropriate units. IL =

Answer 1

The resistance or reactance of the inductor in the presence of AC voltage is

'

The current is

given V = 10.8 V

L = 24 mH = 0.024 H

a) When f = 100 Hz

b) When f = 100 kHz
