An alternating current generator has an internal resistance

Last updated: 7/10/2022

An alternating current generator has an internal resistance Rg and an internal inductive reactance of magnitude Xg. It is used to supply power to a passive load consisting of a resistance R₁ (fixed) and a capacitive reactance of magnitude Xc. For maximum power to be delivered from the generator to the load the value of X, is equal to : Rg Xg Equal and opposite of reactance of generator. Equal in magnitude of impendence of generator.
