4.165 mw value of rl such that, the load average power is maximum is thevenin equivalent circuit as seen by rl
Thevinin's theorem: In any linear active bilateral network consisting of energy sources, Resistances etc with open output target terminals defined can be converted into a simple network consisting of voltage source in series with Resistance.
Maximum Power transfer theorem: In any linear active bilateral network consisting of energy sources with their internal resistances is deriving an external load, then maximum power is transferred to the load when load resistance is equal to equivalent source resistance seen by it.
Rth: while calculating Rth Independent voltage soure gets short opera circuited and Independent current source gets open circuited.
