Q12. Fig Q3 shows a single stage transistor amplifier. The voltage between base and emitter is 0.3 V and the d.c. voltage at the output terminals is 8 V.

(a) Calculate EACH of the following, assuming the base current is small enough to be neglected:

(i) The voltage between emitter and collector;

(ii) The power developed in the 150Ωresistor;

(iii) The power dissipated in the transistor.

(b) Sketch the circuit diagram and show the additional components needed to make the amplifier suitable for amplifying small a.c. signals.
