Question
The output of the given circuit in Figure.
✓
Answer
(a) would be like a half-wave rectifier with negative cycles in output
Explanation: When the positive cycle is at A, the diode will be in forwarding bias, and resistance due to diode is approximately zero the current in the circuit is maximum so potential across the diode will be about zero. Similarly, when there is a negative half cycle at A, the diode will be in reverse bias and resistance will be maximum so potential difference across the diode is $V_m \sin \omega t$ with negative at A.
