Question

To use a transistor as an amplifier 

(a) the emitter base junction is forward biased and the base collector junction is reversed biased 

(b) no bias voltage is required 

(c) both junction are forward biased 

(d) both junction are reverse biased

Answer 1

The correct option is (a) the emitter base junction is forward biased and the base collector junction is reversed biased.

Explanation:

To use transistor as an amplifier the emitter base junction is forward bias while the collector base junction is reverse biased.
