An npn-transistor is connected in common-emitter configuration in a given amplifier. A load resistance of 800 Ω 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 circuits is 192 Ω, the voltage gain and the power gain of the amplifier will, respectively, be
4, 4
4, 3.69
4, 3.84
3.69, 3.84
To solve this problem, we need to find the voltage gain and power gain of the amplifier.Given:• Load resistance • Voltage drop across V• Current amplification factor (• Input resistance First, calculate the collector current AmAThe base current is given by:AThe input voltage is:VThe voltage gain is calculated as:Next, calculate the power gain Output power WInput power WTherefore, the voltage gain is 4 and the power gain is 3.84.This corresponds to Option 3.
