In the following common emitter configuration, an n-p-n transistor with current gain, β=100 is used. The output voltage of the amplifier will be

a
10 mV
b
0.1 V
c
1.0 V
d
10 V

detailed solution

Correct option is C

Given that,β=100Ri=1kΩRL=10KΩVi=ΔVBE=1mvvoltage gainAV=ΔVCEΔVBE=β×RLRiΔVCE=ΔVBE×β×RLRIΔVCE=1×10−3×100×101=1.0V
