: A device used to open or close the circuit path. An "open" circuit has a break that stops current flow; a "closed" circuit is a complete loop.
: Conductive materials, usually copper wires, that provide the physical path for electricity to travel. Introduction to Electric Circuits
: Provides the electrical "pressure" (voltage) to move charges. Examples include batteries (DC) and wall outlets (AC). : A device used to open or close the circuit path
: A device that consumes electrical energy and converts it into another form, such as a light bulb (light), a motor (motion), or a heater (heat). : Provides the electrical "pressure" (voltage) to move
An electric circuit is an unbroken, closed loop of conductive material that allows electric charges (electrons) to flow continuously from a power source, through various devices, and back again. Essential Components of a Circuit
The behavior of circuits is governed by fundamental relationships between three primary variables: a basic introduction to electrical circuits
