Impedance is the complex form of resistance. Impedance takes into account capacitance and inductance in a circuit as well. Impedance can be represented as resistance as a function of frequency.

AnswerImpedance is not a 'complex form of resistance'. It is the vector sum of a circuit's resistance and reactance. In electrical engineering, 'resistance' has a very specific meaning, and cannot be used to denote 'opposition'.
Never heard the word "impedence".
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.
impedance is the combination of a resistor and a inductanceor capacitance.
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Impedence
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
In the USA, should be 500 or 600 Ohms. It is 600 ohms as standard
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
A buffer amplifier can be used to transform high input impedence to low output impedence, or vice-versa.
Resistance divided by impedence
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Yes, you can plug an electric guitar into an acoustic amplifier. But I would suggest that you don't play at a high volume for a long period of time of the difference in impedence - an acoustic guitar (and bass and vocals) is low impedence, where an electric guitar (& keyboard) is high impedence.
remais same.......
Impedence
to calculate impedence of power supply
This question makes no sense, however, one answer may be to determine the impedence of the computer. The conductivity would be the reciprocal of the impedence. At full power a computer with a 200 amp power supply would have an impedence of approximately .02 ohms. If so, the conductivity would be 50 mhos. Difficult and confusing question.... best I can do.
very high value
reflected impedence is a tool to analyse resonant coupling..
