This document contains definitions of electrical terms like circuit, circuit breaker, and battery, as well as brief descriptions of plugs and the Empire State Building. A circuit is a path that allows electrical current to flow with a power source like a battery. A circuit breaker automatically cuts power to protect a circuit from damage. Batteries use an anode, cathode, and electrolyte to generate a flow of electrons. Plugs are used to stop up holes or gaps. The Empire State Building is a 1,250 foot tall skyscraper in New York City located between West 33rd and 34th streets on Fifth Avenue.
