The output of the given circuit in Figure

Options

A. would be zero at all times.
B. would be like a half wave rectifier with positive cycles in output.
C. would be like a half wave rectifier with negative cycles in output.
D. would be like that of a full wave rectifier.

Answer

C

Explanation

When A is the positive terminal, the diode is said to be in forward resistance and resistance would be zero. The potential difference across the diode is noted to be in forward bias and we record a pulsating voltage, varying from '0' to 'V_(m)', in a sinosodal manner.
When A is the negative terminal, the diode is said to be reverse biased and the circuit is an open circuit with resistance being maximum and current being zero. Hence, the circuit acts
as a 'half wave rectifier' with positive cycles in output. Hence, the answer is 'B'.
