| static electricity
Electric charge that has accumulated on an object. Static electricity is often created when two objects that are not good electrical conductors are rubbed together, and electrons from one of the objects rub off onto the other. This happens, for example, when combing one's hair or taking off a sweater. Sudden releases of built-up static electricity can take the form of an electric arc. See Note at electric charge. |
