ALPHA (?):?It is a large signal current gain in common base configuration. It is the ratio of collector current (output current) to the emitter current (input current).It is a current gain in CB amplifier and it indicates that the amount of emitter current reaching to collector. Its value is unity ideally and practically less than unity. Beta (?): It is a current gain factor in the common emitter configuration. It is the ration of collector current (output current) to base current (output current).
74) In P-N- P transistor operating as an amplifier with common emitter configurations a change in base current from 100 mA to 200 mA produces a change in collector current from 10 mA to 18 mA. The current gain of transistor is
