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 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
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 will be the characterstics impedence if the length of the cable is doubled?
remais same.......
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 is the conductivity of a computer?
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.
An accurate voltmeter must have an internal impedence of?
very high value
What is meant by reflection?
reflected impedence is a tool to analyse resonant coupling..
