Answer – B. To reduce the effects of re'
The answer to the question, for a common emitter amplifier, the purpose of swamping is to reduce the effects of re'.
Solution:
To stabilize the Voltage gain and reduce the distortion, we use a swamping resistor which is unbiased resistance in the emitter terminal of the common emitter amplifier.
Therefore, for a common emitter amplifier, the purpose of swamping is to reduce the effects of re'. Hence, Option (B) is the correct answer.
