Text Solution

Verified by Experts

1. Collector end is reverse biased and base - emitter ends forward - biased
2. A small variation in the base current produces a large variation in the collector current with a phase difference of `180^(@)` between them, without altering the input frequency. this is the basis of an amplifier circuit.
3. Power gain of the amplifier in CE mode is given by,
4. The input and out put currents are as shown in the figure above.
