A common emitter amplifier circuit is shown in the figure below. For the transistor used in the circuit the current amplification factor, dc =100 . Other parameters are mentioned in the figure. We find that :

1. A. V BE =+18.2 , V , ; V BC =-3.45 , V and amplifier is working
2. B. V BE =+18.5 , V , ; V BC =+2.85 , V and amplifier is not working
3. C. V BE =+20.7 , V , ; V BC =+3.75 , V and amplifier is not working
4. D. V BE =+21.5 , V , ; V BC =-2.75 , V and amplifier is working
