Let's explain why Common Emitter (CE) configuration is preferred over Common Collector (CC) for amplification purposes.
Common Emitter amplifier is an amplifier that offers high current gain, medium input resistance and high output resistance.
Common Collector is another type of amplifier where the input signal is applied to the base and the ouput signal is taken from the emitter.
The Common Emitter configuration is preferred over the Common Collector configuration because the Common Emitter offers a high power gain(high voltage and current gain), and has a lower resistance when compared to the Common Collector configuration.
ANSWER:
The common Emitter configuration has higher voltage and current gain when compared to the Common Collector configuration.
