Q1: In a semi converter feeding a resistive load

A the waveshapes of output voltage and output current are exactly similar

B the waveshapes of output voltage and output current can not be similar

C the waveshapes of output voltage and output current are similar only for low values of firing angle

D the waveshapes of output voltage and output current may be similar or dissimilar

ANS:A - the waveshapes of output voltage and output current are exactly similar

Because in resistive load current wave is in phase with voltage.
