Maximum Average Power Transfer Theorem and it's Derivation (ac circuit)
Maximum Power Transfer Theorem for AC circuits:
This theorem gives the impedance conditions in AC circuit for maximum power transfer to a load. It states that in an active AC network consisting of source with internal impedance Zth which is connected to a load ZL, the maximum power transfer occurs from source to load when the load impedance is equal to the complex conjugate of source impedance Zth.
