Fundamentals of Electricity

Electricity exists everywhere, from high voltage power lines to phones and computers. Understanding the basics of how it works remains essential to using it safely and efficiently. This article will describe some of those basic fundamentals of electricity. Electron Flow At its core, electricity consists of the movement of electrons through a substance. Some materials, like copper and aluminum, allow electrons to flow much more easily. Furthermore, materials like rubber and ceramic resist electron flow and are said to have high resistance. Resistance, measured in units of Ohms, describes how easily electrons move through a material. An analogy for electron
