What does an amp measure?

An ampere, often shortened to amp, measures electric current in a circuit. This unit quantifies the flow of electric charge, specifically, it indicates the number of coulombs (the basic unit of electric charge) that pass through a conductor in one second. Understanding electric current is crucial for evaluating how much electricity is being consumed or transmitted in a circuit, which plays a vital role in the design and analysis of electrical systems.

In the context of electric circuits, it helps to distinguish between related concepts such as voltage, which represents electric potential, and power consumption, which is a product of current and voltage. Recognizing the role of amps in measuring current allows individuals to analyze and troubleshoot electrical systems effectively, enhancing their overall electrical knowledge and practical skills.
