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 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.
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.
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.
How would you calculate the admittance if you were given impedance?
To calculate the admittance if you are given the impedance, you take the inverse of the impedance ( that is 1/z).
What are applications of smith chart?
1) A normalized load admittance of (0.2 + j0.2) needs a single stub tuner. i) how far down the line should it be located? ii) what is normalized admittance at the point just to right of where stub should be attached? 2) A certain point along a transmission line the normalized admittance is (1+j1.5) i) Design the short-circuited stub necessary to change the normalized admittance to (1+j0) I would prefer the use and explanation of a smith chart. If you want to solve analitically feel free to do so.
What is function of mho relay?
OFFSET IMPEDANCE RELAYOffset impedance relay is also known under names ADMITTANCE RELAY or MHO RELAY
What is the ratio of apparent power to true power?
The ratio of apparent power to true power is called 'admittance', expressed in siemens. Admittance is the inverse of impedance.

What is admittance why it used in electrical?
Admittance is the reciprocal of impedance (1/Z) and is the vector sum of conductance (1/R) and susceptance (1/X). Admittance is used in solving parallel alternating-current circuits, because it avoids the need to vectorially add or subtract reciprocals, which would be the case if we were to use impedance, resistance, and reactance.
What is microsiemens?
A siemens is a unit of conductance or admittance, expressed as the reciprocal of resistance or impedance. (Siemens = 1/ohms) One microsiemens is 1 megohm.
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 is a sentence with the word admittance in it?
He was refused admittance to the club.His admittance was a shock to the courtroom.
What is a sentence for admittance?
The cost of admittance into the Comic Con was 10 dollars. This is an example of admittance.
What is admittance?
Admittance is the act of admitting or permission to enter.
How do you convert percent impedance of transformer to impedance value?
The apparent impedance looking into a transformer from one side will not be the same as looking in it from the other, which is why percent impedance is used. If you are looking from the high voltage winding (I'm labeling #1) to the low voltage winding (#2), you must scale the percent impedance as follows: (% impedance) x (Winding #1 nominal voltage)^2 / (transformer base VA)
