What is current?
Electric current is the flow of electric charge, usually electrons moving through a wire. The SI unit is the ampere (amp), one coulomb of charge passing per second, named after André-Marie Ampère. Current, voltage and resistance are linked by Ohm's law: current = voltage ÷ resistance.
Everyday currents span a huge range: a phone draws a few hundred milliamperes, a kettle about 10 A, a car starter motor a few hundred amps and a lightning bolt around 30,000 A.

Frequently asked questions
How many milliamps are in an amp?
1,000 mA = 1 A.
How much current is dangerous?
Currents through the body above about 30 mA can cause cardiac arrest; household circuit breakers trip at 10–32 A to prevent fires, and RCDs/GFCIs trip at 5–30 mA to protect people.
