A 60-Hz alternating voltage having a rms value of 1 00 V is applied to a series RL circuit by closing a switch. The resistance is 15 n and the inductance is 0.12 H. (a) Find the value of the dc component of current upon closing the switch if the instantaneous value of the voltage is 50 V at that time. (b) What is the instantaneous value of the voltage which will produce the maximum dc component of current upon closing the switch? (c) What is the instantaneous value of the voltage which will result in the absence of any dc component of current upon closing the switch? (d) If the switch is closed when the instantaneous voltage is zero, find the instantaneous current 0.5, 1 .5, and 5.5 cycles later
