What load impedance Z will result in maximum power transfer from an electric source with an internal impedance of r?
EcclesJordanTrigger
For maximum power transfer, source resistance should match load resistance and source reactance should match load reactance with the opposite sign (so if the load is capacitive, the source should be inductive).

What is the purpose of 50 ohms antenna?
A; it is to match the cable line impedance to the receiver for maximum transfer of energy
What are the importance of impedance matching in amplifiers?
Two reasons. 1...When impedance of source and destination match, power transfer is maximum. 2...If a long transmission line is involved, the characteristic impedance of the line must match the destination impedance, or reflections will occur on the line.
Does the maximum power transfer condition states maximum efficiency condition?
Answer Pmax=E^2/(4xRs) The maximum power is transferred when the load impedance is the complex conjugate of the source impedance. For a dc circuit or a purely resistive circuit, the load resistance equals the source resistance.
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
What is dynamic impedance?
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
What will happen in case of AC circuit for maximum power transfer 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
What are the advantages of Transformer coupling method?
transformer coupling ensures maximum power transfer is obtained even if the output impedance is not equal to the load impedance
What is the condition of maximium power transfer of circuit?
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.
What is the purpose of 50 ohms antenna?
A; it is to match the cable line impedance to the receiver for maximum transfer of energy
Why is impedance matching used in electronics?
Impedance matching is used in electronics to get an electronic device with an input and output source to work. Impedance matching will give the electronic it's maximum transfer of voltage. An example of this are FM radio receivers.
Why you go for maximum power transfer?
Z=(R^2+(Xl*Xc)^2)^1/2 impedance equcation
What are the importance of impedance matching in amplifiers?
Two reasons. 1...When impedance of source and destination match, power transfer is maximum. 2...If a long transmission line is involved, the characteristic impedance of the line must match the destination impedance, or reflections will occur on the line.
Which transistor configuration has the highest input impedance?
Common Emitter Configuration has maximum impedance.
Does the maximum power transfer condition states maximum efficiency condition?
Answer Pmax=E^2/(4xRs) The maximum power is transferred when the load impedance is the complex conjugate of the source impedance. For a dc circuit or a purely resistive circuit, the load resistance equals the source resistance.
Applications of maximum power transfer theorem?
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.
Is an audio signal affected by wire gauge?
Absolutely for maximum power transfer impedance's are to be matched a low wire gauge will insure that the power is not dissipated on the wire as appose in the speakers.
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
