What does amperage refer to in electrical terms?

Amperage refers specifically to the flow of electric current in a circuit. Measured in amperes (amps), it quantifies how much electricity is flowing through a conductor over a given period of time. This current flow is crucial for the functioning of electrical systems, as it determines how much charge passes through a point in the circuit.

In contrast, voltage level refers to the potential difference that drives the current, electrical resistance measures how much a material opposes the flow of current, and power output combines current flow and voltage to indicate how much energy is being used or produced. Understanding amperage is vital for diagnosing electrical issues and ensuring that circuits are adequately sized to handle the load without overheating or causing damage.
