An alternating current generator has an internal resistance Rg and an internal reactance Xg. It is used to supply power to a passive load consisting of a resistance Rg and a reactance XL. For maximum power to be delivered from the generator to the load, the value of XL is equal to
For maximum power delivered, we must have only resistance no net reactance due to inductor and capacitor. So, to make the reactance zero, XL must be equal to -Xg. Hence, correct option is (b).
