Which quantity is measured in amperes?

• A. Current
• B. Voltage
• C. Resistance
• D. Frequency

Answer: (A)

Current is the rate at which electric charge flows through a conductor. Amperes quantify that rate—one ampere equals one coulomb of charge passing a point each second. This is why current is measured in amperes. The other quantities are separate: voltage is the electrical potential difference (volts), resistance is how much a material opposes current (ohms), and frequency is how often a repeating event occurs per second (hertz).
