An alternating current generator has an internal resistance \(R_{g}\) and an internal reactance \(X_{g}\). It is used to supply power to a passive load consisting of a resistance \(R_{g}\) and a reactance \(X_{L}\). For maximum power to be delivered from the generator to the load, the value of \(X_{L}\) is equal to:
1. zero
2. \(X_g\)
3. \(-X_g\)
4. \(R_g\)

(c) Hint: For maximum power to be delivered from the generator to the load, the total reactance must vanish.
Step 1: For delivering maximum power from the generator to the load, total internal reactance must be equal to the conjugate of total external reactance.
Hence,                        Xint = Xext
                               Xg = XL*=-XL
                               XL = -Xg
