C) stiff to the output resistance of the collector.
D) stiff to the input resistance of the emitter.

Question

Quizplus · Accepted Answer

In a voltage-divider bias circuit, the voltage divider network is used to set the base voltage of the transistor. The input resistance of the base is relatively high, so it is important that the voltage divider network appears stiff (i.e., does not change significantly with changes in the input resistance) in order to maintain the bias voltage at the desired level. Therefore, choice A is the best choice.
