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 (a) zero. (b) Xg. (c) – Xg. (d) Rg .
Correct option is C) Generator Rg,Xg Passive load Rg,XL The condition for the power to be maximum is the veactance should be zero. Xg+XL=0 XL=−Xg
