Final answer:
Electrical current is the flow of electric charge carriers, driven by the movement of electrons in a circuit, and can power electrical devices or systems.
Explanation:
Electrical current is caused by the movement of electrons in a circuit. It is the flow of electric charge carriers, typically measured in amperes (A).
When a circuit is closed, allowing electrons to move through it, they create an electrical current that powers electrical devices or systems.
A short circuit, which provides a low-resistance path for the current, can lead to a rapid flow of electrons and potential hazards like overheating or electrical fires.
