Maximum Power Transfer Theorem

This theorem is used to find the value of load resistance for which there would be maximum amount of power transfer from source to load.
Maximum power transfer theorem states that “In any linear bilateral network the maximum power will be delivered by the load, when the load resistance is equal to the source resistance.
i.e RL = RS.


IL = Vth /(RL+Rth) [RS = Rth]
Pmax = Vth
2/4Rth
