A npn transistor is connected in common emitter
configuration in a given amplifier. A load resistance
of 800 ``\Omega`` is connected in the collector circuit and
the voltage drop across it is 0.8 V. If the current
amplification factor is 0.96 and the input resistance
of the circuit is 192``\Omega``, the voltage gain and the
power gain of the amplifier will respectively be :
(1) 4, 3.84
(2) 3.69, 3.84
(3) 4, 4
(4) 4, 3.69
