A transistor amplifier is shown in Fig. 21.27. The parameters of the
transistor are hie = 2 k, hoe = 25 S and hfe = 55, and the output load
resistor dissipates a signal power of 10 mW. Determine the power
gain of the stage and the input signal e.m.f. E. The reactances of the
capacitors may be neglected
