When measuring amps, what quantity is being measured?

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

Answer: (B)

Amps measure the current—the rate at which electric charges flow through a conductor. The ampere quantifies how much charge passes a point each second, and an ammeter is placed in series to capture the same current that powers the circuit. Voltage is the potential difference (volts), resistance is how much a component opposes current (ohms), and power is the rate of energy transfer (watts) that relates to both voltage and current via P = V × I. So, measuring amps is measuring the current.
