Maximum power transfer

Cuthbert Nyack
This states that the power delivered to a load is a maximum when the load resistance is equal to the output(thevenin) resistance of the circuit.

The applet above shows a circuit with output resistance 6/11ohms. If a resistor R is connected to the circuit at the terminals AB and R varied then the power dissipated in R is a maximum when R = 6/11ohms. The maximum tends to be very wide.
