show that the power absorbed by the load is half the power delivered by source when the load and source impedances are conjugates.

The Maximum Power Transfer Theorem is a principle in electrical engineering that states that the maximum amount of power can be transferred from a power source to a load when the impedance of the load is equal to the complex conjugate of the impedance of the source.
The Maximum Power Transfer Theorem is important because it allows for the efficient transfer of power from a source to a load. By ensuring that the impedance of the load is matched to the source, the maximum amount of power can be delivered without any power being lost due to mismatched impedances.
The Maximum Power Transfer Theorem is applied in practical circuits by using matching networks or impedance matching circuits. These circuits are designed to match the impedance of the load to the source, thus maximizing the power transfer.
One limitation of the Maximum Power Transfer Theorem is that it assumes that both the source and the load are linear and passive. This means that the theorem may not apply to circuits with non-linear or active components. Additionally, the theorem only applies to DC circuits and may not be applicable in AC circuits.
The Maximum Power Transfer Theorem is closely related to Ohm's Law, which states that the current through a conductor is directly proportional to the voltage and inversely proportional to the resistance. The impedance of a circuit is a combination of resistance, capacitance, and inductance, and the Maximum Power Transfer Theorem aims to match the impedance to maximize power transfer, just as Ohm's Law aims to find the optimal current for a given voltage and resistance.
