Current is the flow of electric charge in a circuit. It moves through materials such as wires. Current is present when a circuit is complete. It is an important part of electrical systems.

Current is found in devices such as lights, computers, and appliances. It is measured in units called amperes, or amps. Electrical systems around the world use current to power equipment.

Current is part of how electricity is used in daily life. It is present in many technologies and systems. This flow of charge is studied in science.
