Which term describes the flow of electric charge through a circuit, measured in amperes?

• A. Current
• B. Resistance
• C. Input
• D. Output

Answer: (A)

The flow of electric charge through a circuit is current, and it is measured in amperes. This term describes how much charge passes a point each second, so it directly captures the rate of flow. Resistance, on the other hand, describes how much a component opposes that flow and is measured in ohms. Input and output are general terms that don’t specify a physical quantity for electrical circuits. In formulas, current equals the amount of charge transferred per unit time, and one ampere is one coulomb per second.
