For CE transistor amplifier, the audio signal voltage across the collector resistance of is 4 V. If the current amplification factor of the transistor is 100 and the base resistance is
, then the input signal voltage is
10 mV
20 mV
30 mV
15 mV
As we learnt in
Transistor -
Three layered semiconducting device .
NPN or PNP
- wherein
1. Emitter is heavily doped
2. collector is moderately doped .
3. Base is lightly doped & very thin
B=100
Option 1)
10 mV
This solution is incorrect
Option 2)
20 mV
This solution is correct
Option 3)
30 mV
This solution is incorrect
Option 4)
15 mV
This solution is incorrect
