How you can find real and imaginary parts of impedance if impedance and angle is given?
Real part = (magnitude of total impedance) x (cosine of the angle) Imaginary part = (magnitude of total impedance) x (sine of the angle)
Characteristic impedance of coaxial feeder proportional to its length inversely proportional to its length or constant to its length?
The characteristic impedance of a coaxial feeder doesn't depend on its length.The number is printed on the jacket of the cable, and applies equally to a1-meter section or a 500-meter section.The effective impedance of a coaxial feeder depends on its length if it's not terminatedin the characteristic impedance. The relationship is not a simple proportion, and thisimpedance is a complex quantity.
Does impedance matter with a y-y bank of transformers?
No. Only if your paralleling them.
What is meant by the terms acoustic impedance and attenuation?
Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
What is 52 x 4 at 4 ohms?
52 x 4 is always 208, regardless of the impedance.
The property of a conductor that impedes the flow of charge is called?
Resistance or impedance.

What has the author I G Black written?
I G. Black has written: 'A composite impedance function'

Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
Can an impedance matching device reduce electrical costs?
An impedance matching device is used to test the resistance, inductive reactant and capacitive reactant in a circuit. If one component did not match the impedance of the conductor, some of the current will be lost by the conductors itself. In conclusion if electricity is lost, the component needs to meet its regular voltage. It consumes more voltage than expected because of the loss. Impedance matching device can actually reduce electrical cost.
What does impedance mean and how does it affect RG6 cables?
Impedance is similar to resistance, but with an extra property called reactance that only affects AC signals. A steady DC signal only "sees" the resistance of a circuit or a cable, while AC "sees" both the resistance and the reactance. The resistance plus the reactance equals the impedance. The reactance includes both capacitance (a tendency to store electrical energy) and inductance (a tencency to store magnetic energy). For cables like RG6, the DC resistance is very low, only an ohm or less per hundred feet, while the impedance is 75 ohms. The impedance value of the cable is determined by the outer diameter of the center conductor, the inner diameter of the outer conductor, and electrical properties of the material between the two (the dialectric). For practical purposes, the only thing that really matters is that the impedance of the cable needs to be the same as the impedance of any connectors or adapters and the signal source and destination (load) it is used with. When one of those elements has a different impedance, some of the signal tends to reflect back to the source instead of continuing to the destination. Coaxial cables are generally used when it is important to preserve as much signal as possible between the source and the destination, as in broadcasting, or to protect the signal from external interference. The outer conductor is generally grounded and blocks interference from reaching the inner conductor, which carries the signal.
How to distinguish between characteristic impedance and input impedance?
The characteristic impedance or surge impedance belongs to uniform transmission lines.In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground). In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
Input impedance is greater than to load impedance?
In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Is characteristics impedance of a filter is same as output or load impedance?
load impedance
What is analog audio impedance?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
