Solution
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.
