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. 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 flow involves thinking of a pipe with water flowing through it.

An Explanation of Photovoltaics

Photovoltaics employ solar panels to create energy. Solar power remains a rapidly growing field in the renewable energy sector. It has the potential to completely power our world and drastically reduce greenhouse gas emissions. The Photovoltaic Effect Originally discovered by Alexandre-Edmond Becquerel in 1839, the photovoltaic effect takes advantage of the tendency of certain materials to release electrons when exposed to sunlight. When a positive back plate and negative front conductors are placed on either side of a photoelectric material, free electrons travel from the back plate to the front conductors, hence generating electric current. This current is then captured

Electrical Contractor Pre-Fab Strategies for Increased Profitability

A variety of ways exist to quickly and efficiently complete an electrical installation. One method involves using pre-made and pre-fabricated conduits, cables, panels, and devices. Pre-fab strategies cut down on repetitive labor costs and scrap material waste. Furthermore, pre-fabricated components are assembled in quality-controlled factories by highly trained technicians. This ensures that every device and termination is in working order and properly connected. These technicians work faster and cost less per hour than a journeyman electrician, therefore saving the contractor time and money. Custom Bundled Cables When pulling multiple wires into a conduit or tray system, wire organization can quickly
