Redraw the circuit:

\

Maximum Power Transfer:

\

For any power source, the maximum power transferred from the power source to the load is when the resistance of the load $\"\"$ is equal to the equivalent or input resistance of the power source $\"\"$

\

Observe the circuit:

\

$\"\"$ is in parallel with $\"\"$ .
