Verified step by step guidance1
Understand that electrical current is the flow of electric charge through a conductor per unit time.
Recall that the SI unit for electrical current is defined as the ampere (A), which measures the amount of charge passing a point per second.
Recognize that watt (W) is the unit of power, ohm (Ω) is the unit of electrical resistance, and volt (V) is the unit of electric potential difference.
Identify that among the given options, only ampere (A) correctly represents the SI unit of electrical current.
Conclude that the correct SI unit for electrical current is ampere (A).
