Solution
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.
