Question

A good diode checked by a multimeter should indicate ______.

पर्याय

• high resistance in reverse bias and a low resistance in forward bias.

• high resistance in both forward bias and reverse bias.

• low resistance in both reverse bias and forward bias.

• high resistance in forward bias and low resistance in reverse bias.

Answer 1

A good diode checked by a multimeter should indicate high resistance in reverse bias and a low resistance in forward bias.

Explanation:

In forward bias, the depletion layer diminishes, facilitating the movement of charge carriers across the junction, hence resulting in reduced resistance. In reverse bias, the depletion layer expands, blocking the movement of charge carriers and resulting in high resistance. A working diode should clearly exhibit this difference.
