In common emitter transistor configuration, the input signal is applied between the base and emitter terminals of the transistor and output appears between the collector and __________ terminals.
Correct Answer: B — Emitter
The correct answer is B: Emitter.
In the common emitter (CE) configuration, the emitter terminal is common to both the input and output circuits — hence the name.
Input: Applied between the base and emitter terminals.
Output: Taken between the collector and emitter terminals.
A small base current controls a much larger collector-to-emitter current, enabling amplification.
Advantages of Common Emitter Configuration:
High voltage gain — suitable for amplification applications.
High current gain — efficient control of output current with small input current.
Inverts the input signal (180° phase shift).
Disadvantages:
Lower input impedance compared to common base or common collector configurations.
Relatively high output impedance.
Applications:
Audio and radio frequency amplifiers.
Digital switching circuits.
