Definition
Static electricity (noun): A stationary electric charge, typically produced by friction, that causes objects to attract or repel each other or to produce sparks.
Usage
This term is used to describe the buildup of an electrical charge on the surface of an object. It is called "static" because the charge does not flow as a current but remains in one place until it is discharged.
Examples
- When you rub a balloon on your hair, you create static electricity that makes your hair stand up.
- The shock you feel after walking on a carpet and touching a metal doorknob is caused by static electricity.
- Static electricity can be a problem in dry climates and can damage sensitive electronic components.
Advanced Usage
- Triboelectric effect: This is the scientific term for the generation of static electricity through friction between two different materials.
- Electrostatic discharge (ESD): This refers to the sudden flow of static electricity between two electrically charged objects, which is the cause of the familiar spark or shock.
Variants and Related Words
- Static charge: A more general term for the accumulated charge itself.
- Electrostatics: The branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges, including static electricity.
Synonyms
- Triboelectricity
- Frictional electricity
Related Phrases
- To build up a static charge: To accumulate static electricity.
- Synthetic fabrics can easily build up a static charge.
- To discharge static electricity: To release the built-up charge.
- You should touch a grounded metal object to discharge static electricity before handling the computer parts.
Noun
- electricity produced by friction
