For maximum power transfer the load resistance should be equal to the source resistance.
An often misunderstood theorem. It applies strictly where one wishes maximum power transfer.
It was misused for example in early power systems by trying to match the generator resistance to the load resistance.
And it has little application in audio systems, where Power is much less important than Distortion. [for least distortion, the output impedance of the amplifier should be less than 10% of the impedance of the load.]

keep a charged body near it. the condition is that when we it connected to the ground.
Impulse-momentum theorem
we can minimise the loss of energy due to practically a non-resistance condition.
Impulse-momentum theorem
According to maximum power transfer theorem for ac circuits maximum power is transferred from source to load when the load resistance is equal to the magnitude of source impedance. The source imoedance is the thevenin equivalent impedance across the load
boda
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
no
The Maximum Power Transfer Theorem is not so much a means of analysis as it is an aid to system design. The maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the Thevenin/Norton resistance of the network supplying the power.
the practical applications of maximum power transfer theorem are 1:communication systems 2:control systems * radio transmitter design
yes
Increasing the power delivered to load motor in an electric vehicle design and a solar array loaded by a grid tied inverter are some applications of maximum power transfer theorem. Maximizing the power delivered to transmission line or antenna in a radio transmitter final amplifier stage design is another practical application.
I don't see the use of, without a purpose, deliberately seeking a lower power output than possible -- why would you waste energy? If the purpose is to control power, then the maximum power transfer theorem will predict what can possibly be delivered by the system. The theorem is telling you the design is less than ideal if you measure something less, which is always true. You can ask yourself "Can I possibly improve the design?"

Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
In electrical engineering, the maximum power (transfer) theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must be made the same as that of the source. It is claimed that Moritz von Jacobi was first to discover the maximum power (transfer) theorem which is referred to as "Jacobi's law". The theorem applies to maximum power, and not maximum efficiency. If the resistance of the load is made larger than the resistance of the source, then efficiency is higher, since most of the power is generated in the load, but the overall power is lower since the total circuit resistance goes up. If the internal impedance is made larger than the load then most of the power ends up being dissipated in the source, and although the total power dissipated is higher, due to a lower circuit resistance, it turns out that the amount dissipated in the load is reduced.
