In introductory electricity, electric current is measured in which SI unit?

• A. coulomb (C)
• B. volt (V)
• C. ohm ($\Omega$)
• D. ampere (A)

Answer: (D)

Verified step by step guidance

1. Understand that electric current is the flow of electric charge per unit time through a conductor.
2. Recall that the SI unit for electric current is defined based on the amount of charge passing a point per second.
3. Know that the coulomb (C) is the unit of electric charge, volt (V) is the unit of electric potential, and ohm (\Omega) is the unit of electrical resistance.
4. Recognize that the ampere (A) is the SI unit specifically used to measure electric current.
5. Therefore, the correct SI unit for electric current is the ampere (A).
