Which of the following circuit is mostly used as an amplifier?
1
common-base circuit because it has high voltage gain
2
common-emitter circuit because it has high voltage and current gain
3
common-collector circuit because it has high gain
4
a common-emitter circuit is of a little use because it has an extremely low input resistance
