Q1:

In a half wave rectifier, the load current flows

A only for the positive half cycle of the input signal

B only for the negative half cycle of the input signal

C for full cycle

D for less than fourth cycle

ANS:A - only for the positive half cycle of the input signal

In HWR only single diode is used. This diode is forward biased during the positive half cycle of the input signal and reverse biased during the negative half cycle of the input.

The current flows through the diode only when it is in forward biased. So only positive half cycle of the current flows through the load.
