Which term describes the rate of current flow in an electrical circuit?

• A. Voltage
• B. Capacitance
• C. Resistance
• D. Amperage

Answer: (D)

The rate of current flow is amperage. Amperage describes how much electric charge passes a point each second, measured in amperes (A). This is the actual quantity of current flowing through a circuit, and it’s what you monitor with an ammeter in aircraft electrical systems to ensure loads stay within design limits. Voltage, the driving force pushing charges, is not the rate of flow. Resistance is the opposition to current, determining how much flow occurs for a given voltage. Capacitance relates to how much charge a component can store per volt, not the rate of flow through the circuit.
