Best Answer

Look at "Different names for the two impedances Z1 and Z2":

Scroll down to related links and look at "Calculation the damping of impedance bridging or power matching an interface connecting Zout and Zin".

Scroll down to related links and look at "Measurement of input impedance and output impedance".

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.


In a multistage amplifier input impedance is high and output impedance is low justify the statement?

no. input impedance is low & output impedance is high


Why input impedance is in parallel and output impedance is in series?

That is not the case. Scroll down to related links and look at "Measurement of input impedance and output impedance".

What is input and output impedance?

To get all the 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 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.

Why is output impedance kept low?

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.
