Understand that electric current is the flow of electric charge through a conductor.
Recall that the SI unit for electric current is defined based on the amount of charge passing through a point per unit time.
Know that the unit used to measure electric current is the Ampere, symbolized as A.
Recognize that Volt (V) measures electric potential difference, Ohm (Ω) measures resistance, and Watt (W) measures power, so these are not units of current.
Therefore, the correct SI unit for electric current is the Ampere (A).
