\Step 1:
\Find the Thevinins equivalent resistance.
1.Open the load resistor.
\2.Open Current Sources and Short Voltage Sources.
\3.Calculate the Open Circuit Resistance. This is the Thevenin Resistance (RTh).
\Redraw the circuit :
\Maximum power will be transferred when source resistance and load resistances are equal.
\Step 2:
\ and
are in parallel.
and
are in series.
Thevenin Resistance is .
Solution :
\Thevenin Resistance is .
