Electric current is the amount of electrons, or charge, moving past a point every second. It is basically the speed of electron flow. The faster the electron flow, the higher the current.



Current is represented by the letter I. The basic unit for measuring current is ampere. Ampere can be abbreviated to amp or just A.

1 amp = 1 coulomb/sec
Meaning for every amp, there are 6.25x10^18 electrons moving past a point every second.
