Answer the following questions about the circuit of Fig. 4.158 :

a. What happens to the voltage V C if the transistor is replaced by one having a larger value of b?
b. What happens to the voltage V CE if the ground leg of resistor RB2 opens (does not connect to the ground)?
c. What happens to I C if the supply voltage is low?
d. What voltage V CE would occur if the transistor base–emitter junction fails by becoming open?
e. What voltage V CE would result if the transistor base–emitter junction fails by becoming short?
