A 45.1 mH inductor is connected as in the figure to an ac generator with ε_{m} = 30.0 V. What is the amplitude of the resulting alternating current if the frequency of the emf is **(a)**1.40 kHz and **(b)**11.2 kHz?

Step 1

(a) Write the expression for the amplitude of the resulting alternating current .

Step 2

Substitute the given values in equation (4) when the frequency of the emf is 1.40kHz

Step 3

(b) substitute the given values in equation (4)w...
