What is current on electronic devices?
Answer:
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. One Ampere of current represents one Coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
the flow of electricity - v=i*r
Current is measured in amps.
If you know the power (watts) and the voltage (volts) you can calculate the current:
amps = watts/volts
It depends on the device. As above it's measures in amps, and some things will use a high ampage aka a computer, whereas a mobile phone will use a smaller ampage.
There is also volts, whcih is the amount of electricity, phone chargers can use 5v but a laptop charger could be 20-24
really depends on the device
Current in ANY electrical device, including electronic ones is the same
AMPERAGE, AMPS
If you think of electricity as water in a plumbed system then
Volts( potential difference) is like pressure and current ( amps ) is like volume
Imagine a garden hose pipe with an open end :
the water is falling out in a thick stream
~ low volts high amps ( arc welder)
Pinch the end of the pipe and you get a long narrow stream that is a small diameter:
~ High volts ( pressure) low Current (amps~ volume)
Volts * amps = watts (power)
Formulea for current are
Amps = watts/ volts
Amps = sqrt ( watt/res)
Amps = VOLTS / RESISTANCE
