Another name for current is ________________.

The correct answer is amperage because it refers to the measure of electrical current flowing through a circuit. Current is essentially the flow of electric charge, and amperage quantifies this flow in terms of how many coulombs pass through a given point in one second. This measurement is crucial in electrical and HVAC systems to ensure that devices and equipment are operating within their specified limits, preventing potential overloads and ensuring efficient operation.

Voltage, while related to current, specifically refers to the electrical potential difference between two points in a circuit. Resistance measures how much a material opposes the flow of current, impacting how much current can flow for a given voltage. Capacitance relates to the ability of a system to store an electrical charge. Each of these concepts plays a unique role in electrical theory, but amperage directly captures the essence of current.
