The maximum power transfer theorem states that to obtain maximum external power from a power source with internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals.
Under maximum power conditions:
RL = Rth
The current is given by:
The maximum efficiency is given by:
η = 0.5 = 50%
