What is the term for the flow of electric charge in a circuit?

The term for the flow of electric charge in a circuit is current. Current is measured in amperes (A) and represents the movement of electrons through a conductor, such as a wire. It is the actual flow of electricity that powers devices and systems within an electrical circuit.

Voltage refers to the electrical potential difference between two points and is the driving force that pushes current through the circuit. Resistance is the opposition to the flow of current, typically measured in ohms, and determines how much current will flow given a certain voltage. Power is the rate at which electrical energy is transferred or converted and is calculated as the product of voltage and current. Understanding the role of current in electrical circuits is fundamental, as it is essential for the functionality of any electrical system.
