An amplifier operating from a single 15-V supply provides a 12-V peak-to-peak sine-wave signal to a I-ill load and draws negligible input current from the signal source. The de current drawn from the 15-v supply is 8mA. What is the power dissapated in the amplifier, what is the amplifier effeciency?
