Problem 35
Q

Suppose that the current gain of the transistor in Fig. 29–41 is β=iC/iB=85\beta = i_\textrm{C}/i_\textrm{B} = 85. If RC=3.8 kΩR_\textrm{C} = 3.8 \textrm{ k} \Omega, calculate the ac output voltage for an ac input current of 2.0  μA2.0 \; \mu \textrm{A}.

An npn transistor used as an amplifier. I_B is the current produced by E_B (in the absence of a signal), i_B is the ac signal current (= change in I_B).
