The maximum a.c. power output from a class B power amplifier is 10 W. What should be the minimum power rating of the transistor used?

The maximum a.c. power output from a class B power amplifier is 10 W. What should be the minimum power rating of the transistor used? Correct Answer 4W

maximum ac power output voltage = 10W In class b amplifier, only one half cycle is considered. So the minimum power rating is 4W.
