Question

In a CE transistor amplifier, the audio signal voltage across the collector resistance of 2 K Ω is 2V. if the base resistance is 1 K Ω and the current amplification of the transistor is 100 the input signal voltage is, 1 mV, 10 mV, 0.1 V, 1 V

MARKS App · Accepted Answer

We know that Voltage amplification is given by : V 0 V i n = β R L R i ; 2 V m = 100 2 × 10 3 1 × 10 3
