Electrical impedance is the total opposition to current flow. It includes both a resistive, or DC component and a reactive, or frequency-dependant component. Impedance is the same as resistance if the applied voltage is DC. For AC voltage, the reactive components opposition to current flow changes with frequency, so impedance is typically specified at a particular frequency.
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
Zero sequence impedance indicates a homopolar symmetrical component. It is a term used in electrical engineering within a three-phase system of linear combinations.
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

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
transfer impedance is impedance we encounter when an electrical current passing through one element of the system makes a voltage difference in other element of same system. eg:shield in a coaxial cable
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.
