Current

Electric current means, depending on the context, a flow of electric charge or the rate of flow of electric charge. This flowing electric charge is typically carried by moving electrons, in a conductor such as wire.

The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second. Electric current is measured using an ammeter.

The current flowing through a component can be calculated using Ohms law with this equasion :- I = V/R I=amps, V=volts, R=resistance
