If an alternating voltage is applied across a p-n junction diode in series with a load then

Options

  1. Ano voltage appears across load.
  2. Ba pulsating voltage appears across load.
  3. Can a.c. voltage appears across load.
  4. Da d.c. voltage appears across load which is not pulsating.

Correct answer

B. a pulsating voltage appears across load.

Step-by-step solution

An alternating voltage applied across a p-n junction diode in series with a load produces rectification due to the diode's unidirectional conduction properties. During the positive half-cycle, the diode is forward biased, allowing current to flow through the load and producing a voltage output. During the negative half-cycle, the diode is reverse biased, blocking current flow and resulting in zero voltage output. The resulting waveform consists of positive half-cycles only, forming a pulsating DC voltage across the
