If an alternating voltage is applied across a p-n junction diode in series with a load then (a) no voltage appears across load. (b) a pulsating voltage appears across load. (c) an a.c. voltage appears across load. (d) a d.c. voltage appears across load which is not pulsating.

Answer: (b). The diode allows current in only one half cycle, so the load voltage is one-directional but not steady. This is a pulsating voltage. So the answer is (b).

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

Show answer and solution

Answer: (b)

The diode allows current in only one half cycle, so the load voltage is one-directional but not steady.
