What is an ampere used to measure?

An ampere, commonly referred to as an "amp," is the standard unit of measurement for electric current in the International System of Units (SI). It quantifies the flow of electric charge in a circuit. One ampere corresponds to one coulomb of electric charge passing a point in a conductor in one second. This measurement helps describe how much electricity is moving through the circuit at any given time, which is a foundational concept in understanding electrical systems.

Understanding current is crucial for anyone working with electricity, as it influences how devices operate and how safety measures are implemented. By measuring the flow of electricity in amperes, professionals can ensure that circuits are not overloaded and can assess the power requirements of different electrical devices.
