Question: 

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

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).
