Consider an amplifier operating from 10-V power supplies. It is fed with a |sinusoidal voltage having 2 V peak and delivers a sinusoidal voltage output of 15 V peak to a 1-kO load. The amplifier draws a current of 7.5 mA from each of its two power supplies. The input current of the amplifier is found to be sinusoidal with 0.2 mA peak. Find the voltage gain, the current gain, the power gain, the |power drawn from the de supplies, the power dissipated in the amplifier, and the amplifier efficiency
