1. Calculate the values of all three currents in the circuit shown in Fig.
2. For the emitter bias circuit shown in Fig. find IE, IC, VC and VE, VCE for β= 85 and
VBE= 0.7V.
3. Determine how much the Q-point in Fig. will changeover a temperature range where
β increases from 85 to 100 and VBE, decreases from 0.7V to 0.6V.
4. Fig. shows the voltage divider bias method. Draw the d.c. load line and determine the
operating point. Assume the transistor to be of silicon.
