. To use a transistor as an amplifier


A: The emitter base junction is forward biased and the base collector junction is reverse biased

B: No bias voltage are required

C: Both junctions are forward biased

D: Both junction are reverse biased

 

Best Answer

Explanation:

To make a transistor work as an amplifier, the input must be forward-biased, while the output must be reverse-biased.

The input signal is applied to the base-emitter junction, and the output is sent to the base-collector junction through the load.

Final answer:

Hence, the correct option is (A) i.e The emitter base junction is forward biased and the base collector junction is reverse biased
