Answer 2

Answer:

A transitor acts as an amplifier by raising the strength of a weak signal . The DC bias voltage applied to the emitter base junction , makes if rremains it forward baised condition..... Thus a small input voltage result in a large input voltage, which shows that the transistor work as an amplifier....
