Which unit is used to measure electric current?

• A. Amperes (amps)
• B. Volts
• C. Ohms
• D. Watts

Answer: (A)

Electric current is the rate at which electric charge flows through a conductor. The unit that measures how much charge passes per second is the ampere, abbreviated A. One ampere means one coulomb of charge moves past a point each second. That’s why amperes are used to quantify current. Voltage measures the driving force that pushes charges (potential difference), ohms measure how much a component resists the flow (resistance), and watts measure how much power is produced or consumed (P = VI, or I^2R).
