In the following common emitter configuration an NPN 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
Answer
1.0 V
Explanation
Solution
Voltage gain =Input voltageOutput voltage
⇒ Vout = Vin × Voltage gain
⇒ Vout = Vin × Current gain × Resistance gain
= Vin × β × RBERL= 10−3×100×110=1V.
