Battery maximum power formula

Proof of Maximum Power Transfer Theorem

Maximum Power Transfer Theorem - The amount of power received by a load is an important parameter in electrical and electronic applications. In DC circuits, we can represent the load with a resistor having resistance of RL ohms. Similarly, in AC circuits, we can represent it with a complex load having an impedance of ZL ohms.

Maximum power transfer theorem

OverviewMaximizing power transfer versus power efficiencyImpedance matchingCalculus-based proof for purely resistive circuitsIn reactive circuitsSee alsoNotesExternal links

In electrical engineering, 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. Moritz von Jacobi published the maximum power (transfer) theorem around 1840; it is also referred to as "Jacobi''s law". The theorem results in maximum power transfer from the power source to the load, but not maxi…
