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.
What else can I help you with?
What is output impedence?
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
What is zero sequence impedence?
Zero sequence impedance indicates a homopolar symmetrical component. It is a term used in electrical engineering within a three-phase system of linear combinations.
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
What is the combination of winding losses and self induction is referred to as?
Impedence
When A voltage sourcehaving a source impedance Z R jX can deliver maximum Average power to a load impedance Z?
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
What has the author Q S Zhu written?
Q. S. Zhu has written: 'Precision electrical impedence tomography instrumentation'
What is output impedence?

What is zero sequence impedence?
Zero sequence impedance indicates a homopolar symmetrical component. It is a term used in electrical engineering within a three-phase system of linear combinations.
What is maximum power transfer theorem?
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
What is the function of a buffer amplifier in electronics?
A buffer amplifier can be used to transform high input impedence to low output impedence, or vice-versa.
How do you get the power factor?
Resistance divided by impedence
What is transfer 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
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Plug electric guitar to acoustic amplifier?
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.
What is the combination of winding losses and self induction is referred to as?
Impedence
Why are use smith chart?
to calculate impedence of power supply
What will be the characterstics impedence if the length of the cable is doubled?
remais same.......
