What is current?
Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow.
An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge”) flowing past a point in a circuit over a given time. A current of 1 ampere means that 1 coulomb of electrons—that’s 6.24 billion billion (6.24 x 1018) electrons—is moving past a single point in a circuit in 1 second. The calculation is similar to measuring water flow: how many gallons pass a single point in a pipe in 1 minute (gallons per minute, or GPM).
