Chapter 8, Problem 29P

For the transistor configuration in Fig. 8.126:

a. Solve for the currents $I_B,I_C,$ and $I_E,$ using the fact that $V_{BE}$ $=0.7V$ and $V_C{}_E$

$=8V.$

b. Find the voltages $V_B,V_C,$ and $V_E$ with respect to ground.

c. What is the ratio of output current $I_C$ to input current $I_B$?

[Note: In transistor analysis, this ratio is referred to as the dc beta of the transistor ( ${\text{β}}_{dc}$).]
