Question

When an n-p-n junction transistor is used as an amplifier in common emitter mode, ______.

विकल्प

• the base emitter junction is reverse biased.

• the input impedance is high and the output impedance is low.

• input signal is applied between the base and emitter and the output is obtained between collector and emitter.

• the input voltage and the output voltage are in phase.

Answer 1

When an n-p-n junction transistor is used as an amplifier in common emitter mode, input signal is applied between the base and emitter and the output is obtained between collector and emitter.

Explanation:

In the Common Emitter (CE) configuration, by definition, the input signal is always applied between the base and emitter and the amplified output is taken between the collector and emitter.
