Quizplus · Accepted Answer

The input resistance at the base, Rin(base), is typically calculated using the formula Rin(base) = β * re, where β is the transistor's current gain and re is the intrinsic emitter resistance. Without specific values for β and re, the choice closest to typical values for a common emitter configuration is 17 kΩ.
