An ideal diode acts like a switch that closes when
A) the bias voltage is zero.
B) reversed-biased.
C) forward-biased.
D) taken out of the circuit.

Question

Quizplus · Accepted Answer

An ideal diode has zero forward voltage drop and infinite reverse blocking capability. At zero bias voltage, the diode will act as an open circuit. When it is forward-biased, it will conduct current like a closed switch. When it is reversed-biased, there will be no current flow. Therefore, choice C is the correct answer.
