Quizplus · Accepted Answer

When the polarity of the source voltage is reversed, the diode will be reverse-biased and will act like an open circuit, resulting in no current flow through the circuit. Therefore, the current in Figure 16-1(b) will be 0 A. However, since the question specifically asks for the current value assuming the diode is made of silicon, we must take into account the intrinsic reverse saturation current of the diode, which is negligible for most practical purposes. Therefore, we can assume that the current is effectively 0 A. The closest answer choice is A, 0.6 mA, which is the forward current that would flow through the diode if it were forward-biased. However, this answer is not correct for the reverse-biased scenario described in the question. The correct answer is therefore C, 0 A.
