What is the formula for power gain when input gain & output gain is given?..

Answer / Abid Hussain

The power gain (G) of a system can be calculated by dividing the output power (Pout) by the input power (Pin). If the input and output gains are given as voltage gains (Av) or current gains (Ai), you can convert them to power gains using the relations: G = Av^2, G = Ai^2 * Rin, where Rin is the input resistance.
