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 rectance `X_(L)`. For maximum power to be delivered from the generator to the load, the value of `X_(L)` is equal toA. zeroB. `X_(g)`C. `-X_(g)`D. `R_(g)` |

Answer» Correct Answer - C For delivering maximum power from the generator to the passive load, total reactance must vanish, i.e., `X_(L) + X_(g) = 0` or `X_(L) = - X_(g)`. Choice (c ) is correct. |
