Question:

In the circuit in Figure P10.39, the transistor parameters are: $\beta=\infty$, $V_{A}=\infty$, and $V_{B E}=V_{E B}=0.7 \mathrm{~V}$. Let $R_{C 1}=2 \mathrm{k} \Omega, R_{C 2}=3 \mathrm{k} \Omega, R_{C 3}=$ $1 \mathrm{k} \Omega$, and $R_{1}=12 \mathrm{k} \Omega$.

(a) Determine $I_{O 1}, I_{O 2}$, and $I_{O 3}$.

(b) Calculate $V_{C E 1}$, $V_{E C 2}$, and $V_{E C 3}$.
