A silicon diode will allow a continuous current in the forward direction,if the source voltage is
A) greater than 0.7 V.
B) equal to 7.7 V.
C) less than 0.7 V.
D) zero.

Question

Quizplus · Accepted Answer

A silicon diode will only conduct current in the forward direction if the voltage applied across it is greater than its forward voltage drop of approximately 0.7 volts. Therefore, option A is the correct choice. Choices B, C and D are incorrect because either the voltage is too high, too low or zero, leading to non-conduction of the diode in the forward direction.
