A controlled half-wave rectifier has a series resistance, inductance, and dc voltage
source with R2 , L75 mH, and Vdc48 V. The source is 120 V rms at 60 Hz.
The delay angle is 50
. Determine (a) an expression for load current, (b) the power
absorbed by the dc voltage source, and (c) the power absorbed by the resistor.
