Q. Using the small-signal equivalent circuit of a BJT with gm = 0.03 S, β = 75, and VA = 65 V, a load resistor RL is connected from the collector to the emitter, as shown in Figure. The transistor is biased to have a dc collector current of 6 mA.
(a) Calculate vL due to the small change vBE.
(b) Find the corresponding change iB in the base current.
