Observe the diagram.

The resistors are connected in series.

Thevenins voltage is .

Current .

Substitute corresponding values in the above equation.

Step 2 :

Maximum power will be transferred when source resistance and load resistance are equal.

Maximum power dissipated is .

Substitute and in the above equation.

Maximum power dissipated is .

Solution :

Maximum power dissipated is .
