What is the SI unit used to quantify electric current?

• A. Ampere
• B. Coulomb
• C. Ohm
• D. Watt

Answer: (A)

Electric current is the rate at which electric charges move through a conductor. The SI unit for this rate is the ampere, defined as one coulomb of charge passing a point each second. So a current of 1 A means 1 coulomb of charge flows every second. Coulomb is the unit of charge, ohm is the unit of resistance, and watt is the unit of power, which is why the ampere is the correct unit for current.
