Name: (11) The supply voltage VCC equals 9V. The base resistor RB is 42k0 Take 0.6V for the knee voltage of the base-emitter diode. Draw the load line for a short-circuit current of 15mA (a) What is the value of the collector resistor RC in that case? (b) What is then the voltage Vor across the transistor? (c) What is then the current le through the transistor?
