An alternating current generator has an internal resistance `underset(g)(R )` and an internal reactance `underset(g)(X )` . It is used to supply power to a passive load consisting of a resistance `underset(g)(R )` and a reactance `underset(L)(X )`. For maximum power to be delivered from the generator to the load , the value of `underset(L)(X )` is equal to

Answer

C

Explanation

For delivering maximum power from the generator to the load, total internal reactance must be equal to conjugate of total external reactance.
Hence, `underset(int)(X )` = ``
