If you measure 17 V across a diode, it is probably ________.
A)in heavy conduction
B)reverse biased
C)forward biased
D)shorted

Question

Quizplus · Accepted Answer

Diodes allow current to flow when forward biased (typically requiring 0.6 to 0.7 V for silicon diodes) and block current when reverse biased. Measuring 17 V across a diode suggests it is reverse biased, as this indicates it is blocking current, causing a significant voltage drop across it.
