What is power gain of the amplifier?

The power gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal.

How to Calculate Power gain of the amplifier?

Power gain of the amplifier calculator uses power_gain = Power delivered to load/Input power to calculate the Power gain, The Power gain of the amplifier formula is defined as the load power P(l) to the input power P(i), an amplifier provides the load with a power greater than that obtained from the signal source. Power gain is denoted by Ap symbol.
