The theorem results in maximum power transfer from the power source to the load, but not maximum efficiency of useful power out of total power consumed. If the load resistance is made larger than the source resistance, then efficiency increases (since a higher percentage of the source power is transferred to the load), but the magnitude of the ...
For example, a maximum power point tracker is used to extract the maximum power from a solar panel and efficiently transfer it to batteries, the power grid or other loads. The maximum power theorem applies to its "upstream" connection to the solar panel, so it emulates a load resistance equal to the solar panel source resistance. However, the ...
A drawback of resonant coupling theory is that at close ranges when the two resonant circuits are tightly coupled, the resonant frequency of the system is no longer constant but "splits" into two resonant peaks, [85] [86] [87] so the maximum power transfer no longer occurs at the original resonant frequency and the oscillator frequency must be ...
As a result of the maximum power theorem, devices transfer maximum power to a load when running at 50% electrical efficiency. This occurs when the load resistance (of the device in question) is equal to the internal Thevenin equivalent resistance of the power source. This is valid only for non-reactive source and load impedances.
Maximum power can refer to: Maximum power transfer theorem in electronics; Maximum power principle in systems theory; Maximum power point tracking in energy extraction, most commonly photovoltaic solar systems
The red curve shows the power in the load, normalized relative to its maximum possible (which occurs when R L == R S).The black curve shows the power transfer efficiency η, which asymptotically approaches the maximum of 100% as the ratio / increases.
A graph to show the power dissipated in a resistive load (red line) supplied by a source with resistive effects. Also shown is the efficiency, η, (blue line) which is the proportion of the total power dissipated that is dissipated in the load resistance.

I believe "Maximum power transfer theorem" is the more common name for this theorem. I propose renaming the article accordingly. -Roger 19:54, 18 January 2009 (UTC) Correct: I was taught it as the 'Maximum power transfer theorem'. I have even taught it as the 'Maximum power transfer theorem'.
