9. How is static electricity defined?

An electrical charge of varying strengths

An electrical charge at rest within one body, or that transfers from one body to another

An electrical charge with a rating of at least 1.21 gigawatts

An electrical charge that is always in motion

Static electricity occurs when there’s an imbalance of electric charges within or on a material’s surface. This imbalance can be caused by friction, pressure, or an electric field. The charge stays until it can move away through an electric current (like touching a metal object) or an electrical discharge (a spark). While usually harmless to humans, static electricity can damage electronic devices, making electrostatic discharge (ESD) protection crucial in handling electronic components.
