# Peak Value of Output Voltage and Voltage Gain of an Amplifier

Not what you're looking for?

A power amplifier when driven by a current source of 5mA rms and a source resistance of 8k, delivers 12.5W signal power to an 8 load resistance. Find peak to peak value of output voltage.

If the input voltage to the amplifier shows 5 V rms, determine the voltage gain of the amplifier.

The given multiple choice answer is verified and correct. Please show how you arrived at your solution.
