Q1:

In the circuit of figure diode will conduct

A from 90 to 180° in the positive half cycle

B from 30° to 180° in the positive half cycle

C from 50° to 160° in the positive half cycle

D from 30° to 150° in the positive half cycle

ANS:D - from 30° to 150° in the positive half cycle

Diode will conduct when instantaneous value of ac voltage is more than 50 V.
