An inductive load that has a resistive component of 4 ? is connected to an ac source of 120 V (rms) through a half-wave SCR circuit. When the triggering angle of the SCR is 50o , the conduction period is 160o . Calculate the following:

a. Average voltage across the load b. Average voltage across the resistive element of the load c. rms voltage across the load d. Average current of the load e. If a freewheeling diode is connected across the load, calculate the load rms voltage. Assume that the current of the diode flows for a complete half cycle.
