Question by Giancoli, Douglas C., Physics: Principles with Applications, 7th Ed., ©2014, Reprinted by permission of Pearson Education Inc., New York.
Problem 34
Q

If the current gain of the transistor amplifier in Fig. 29–41 is β=iC/iB=95\beta = i_\textrm{C}/i_\textrm{B} = 95, what value must RCR_\textrm{C} have if a 1.01.0-μA\mu \textrm{A} ac base current is to produce an ac output voltage of 0.42 V?

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).
Figure 29-41 An npn transistor used as an amplifier. IBI_B is the current produced by ξB\xi_B (in the absence of a signal), iBi_B is the ac signal current (= change in IBI_B).
