What is the unit of measurement for electrical current?

The unit of measurement for electrical current is the ampere, which is commonly referred to as "amp." This unit quantifies the rate at which electric charge flows in a circuit. Specifically, one ampere is defined as one coulomb of charge passing through a point in a circuit in one second. Understanding this concept is crucial for analyzing electrical systems and performing calculations related to electrical flow.

Other terms serve distinct purposes within the realm of electrical measurements. For instance, a volt measures the electrical potential or voltage, indicating the potential energy per unit charge. An ohm quantifies electrical resistance, which is a measure of how much a material opposes the flow of current. Lastly, a watt represents electrical power, calculated as the product of voltage and current, essentially describing how much work is done per unit of time in an electrical circuit. Each of these units plays a vital role in understanding electricity, but the ampere specifically defines the current itself.
