To Electric Circuits: Introduction

The behavior of circuits is governed by fundamental relationships between three primary variables: a basic introduction to electrical circuits

: 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. Introduction to Electric Circuits

: A reference point and safety feature that provides a return path for current. The Core Laws of Electricity The behavior of circuits is governed by fundamental

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 Core Laws of Electricity An electric circuit

: 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).
