For the circuit of Fig. 4.157:

a. Does V_C increase or decrease if R_B is increased?

---

b. Does I_C increase or decrease if β is reduced?

---

c. What happens to the saturation current if β is increased?

---

d. Does the collector current increase or decrease if V_CC is reduced?

---

e. What happens to V_CE if the transistor is replaced by one with smaller β?
