the impedence should be complex conjugate of an equivalent impedence of the network when viewed from the terminals of the load.
i.e; Z=R-jx

Which transistor configuration has the highest input impedance?
Common Emitter Configuration has maximum impedance.
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.
More the transformer impedance less the fault current... so is a high value of transformer impedance good for it?
It depends a lot on the application, i would go with low impedance transformers if am using the transformers for distribution as it will really increase the the maximum fault current. If am using the transformers as step up specially for generators or to charge capacitors, using a high impedance transformer is a good idea as it will decrease the inrush current of the system. you have to see your application and decide what fit that best.

What are the advantages and disadvantages of maximum power transfer theorem?
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.
Which transistor configuration has the highest input impedance?
Common Emitter Configuration has maximum impedance.
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 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 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.
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
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.
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 is the functions of hammers?
To deliver maximum force in a small area.
Why you go for maximum power transfer?
Z=(R^2+(Xl*Xc)^2)^1/2 impedance equcation
What load impedance Z will result in maximum power transfer from an electric source with an internal impedance of r?
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).
The purpose of transformer percentage impedance?
Inherently, the actual impedance seen at the secondary voltage will be different than that seen at the primary voltage. To make things easy, we use symmetrical components, where transformers are reduced to a p.u. (per unit) impedance. 100 x p.u. is equivalent to the percentage impedance you are referring to. When converted to per unit, a transformer has one impedance, not two, so it does not matter whether you are looking through the transformer from the secondary or the primary.
