a. Sketch the circuit diagram for this rectifier. [2 marks]
b. Calculate the average DC voltage across the 30 Ω load resistor, taking into account the usual approximation that conduction extinction occurs essentially at the impedance power factor angle after 180°. [6 marks]
c. Establish an expression for the current flowing through the 30 Ω load resistor, calculating numeric values for all equation coefficients. [6 marks]
d. Sketch the rectified output voltage and load current if a freewheel diode is placed across the RL load. [4 marks]
