Which quantity is measured in amperes?

• A. Current
• B. Charge
• C. Resistance
• D. Inductance

Answer: (A)

Amperes quantify the flow of electric charge, i.e., the current. Current is the rate at which charge moves through a point in a circuit. One ampere means one coulomb of charge passes that point each second. Charge (coulombs) is the total amount of electricity, while current is how fast that charge is moving. The other quantities—resistance (ohms) and inductance (henries)—describe how the circuit resists flow and how it stores energy in a magnetic field, respectively. To measure current, you use an ammeter placed in series with the circuit.
