What unit is used to measure electric current?

The unit used to measure electric current is the Ampere. The Ampere, often shortened to "Amp," quantifies the amount of electric charge flowing through a conductor in a given time. It provides a direct indication of the flow of electric current, indicating how many electrons pass through a point in the circuit per second.

In the context of electrical systems, understanding the unit of electric current is crucial as it relates to the performance and safety of electrical devices. For example, when dealing with the current ratings of equipment or appliances, knowing how to gauge the amount of current is essential for proper operation and preventing overloads.

Volt measures the electrical potential difference, Ohm quantifies electrical resistance, and Watt signifies electrical power. While these units are interrelated, they serve distinct purposes in the study of electricity.
