Selected Ans.

It states that maximum power is transferred from source to load when the load resistance is equal to thevenin's equipment resistance.         i.e. RL=Rth

Practical applications

1. It helps in making a circuit having maximum power dissipation correctly at load of resistance 

2. It is an essential tool for ensuring successful system design.

Maximum Power Transfer Theorem can be stated as – A resistive load, being connected to a DC network, receives maximum power when the load resistance is equal to the internal resistance known as (Thevenin’s equivalent resistance) of the source network as seen from the load terminals.The Maximum Power Transfer theorem is used to find the load resistance for which there would be the maximum amount of power transfer from the source to the load. Applications of Maximum power transfer theorem  1.In communication system, maximum power transfer is always sought. For example in public address system, the circuit is adjusted for maximum power transfer by making load resistance (speaker) equal to the source resistance (amplifier). When source and load have the same resistance, they are said to be matched. 2.In car engines, the power delivered to the starter motor of the car will depend upon the effective resistance of the motor and the internal resistance of the battery. If the two resistances are equal, maximum power will be transferred to the motor to turn to the engine.
