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.
Q. What are the three transistor configurations? The three configurations are common base (CB),common collector (CC) & common emitter(CE). The connection in which the base
