Understand that electric current is the flow of electric charge through a conductor.
Recall that the SI unit system assigns specific units to physical quantities for standardization.
Identify that the unit of electric current is defined based on the amount of charge passing through a point per unit time.
Know that the SI unit of electric current is the ampere, symbolized as A.
Recognize that watt (W) is the unit of power, volt (V) is the unit of electric potential, and ohm (\(\Omega\)) is the unit of resistance, so they are not units of current.
