Hi! I am having some difficulty solving this excercise:
An amplifier operates with a single 15V supply, delivers a peak-to-peak amplitude sinusoidal signal of 12V to a 1k load, and absorbs negligible current from the signal generator. The continuous current supplied by the 15V supply is 8mA.
What is the power dissipated in the amplifier and its efficiency?
(results: 102mW and 15%)
In the resolution pictured below I have assumed zero input power, because I have no data on it in the text
I solved it by recalculating using \[ V_{RMS} \]
