With a varactor diode,the more it is reversed bias,its capacitance
A) decreases.

D) increases to 27 µF.

Question

Quizplus · Accepted Answer

With a varactor diode, the capacitance is controlled by the reverse bias voltage applied across it. When the diode is reverse biased, the depletion region widens and the capacitance decreases. Therefore, the more it is reversed bias, its capacitance decreases.
