Question

The output of the given circuit is

• A. Negatively rectified half wave
• B. Positively rectified half wave
• C. Negatively rectified full wave
• D. Zero all times

Hint:

In circuits involving diodes, the diode will only conduct when it is forward biased. The shape of the output waveform depends on the type of rectification (half-wave or full-wave) and whether it is positive or negative.

Answer 1

The Correct Option is C

In the given circuit, there is a diode connected in series with a resistor, and the input voltage is of the form \( V_m \sin \omega t \). The diode only allows current to flow in one direction (forward bias). Since the diode conducts only during the negative half of the AC cycle (as shown in the diagram), the output will be a negatively rectified full wave, which means the negative half of the wave is passed through, and the positive half is blocked.
Thus, the correct output is negatively rectified full wave.
