Brush up on some basic electrical theory and deepen your knowledge about electricity. In this post we cover Ohms Law, AC and DC Current, Circuits and More.

Learning a bit about electricity is useful because: It will provide the basics for understanding electrical safety. It will help you to better understand the principles of electrical medical equipment such as electrosurgical devices, defibrillators, temperature measurement etc.

Current electricity is the form of electricity which makes all of our electronic gizmos possible. This form of electricity exists when charges are able to constantly flow . As opposed to static electricity where charges gather and remain at rest, current electricity is dynamic, charges are always on the move.

People depend on electricity constantly, and when the power goes out in a storm or there's a tripped breaker or another problem in an electrical circuit, understanding the basic components of an electrical system can help you get things running again. It's also important to know who is responsible for what portion of your electrical service.

Basic Electricity. Conductor Atom. Insulator atom. Single electron in outer orbit. 120 V 60 Hz Sine Wave Diagram. Current flows in both directions. 120 VAC 60 Hz household power is an example of AC current. There are two changes in polarity and two changes in current direction per cycle. The current in 120 VAC 60 Hz changes direction 120 times ...

Electricity powers our world and our bodies. Harnessing its energy is both the domain of imagined sorcery and humdrum, everyday life -- from Emperor Palpatine toasting Luke Skywalker, to the simple act of ejecting the "Star Wars" disc from your PC. Despite our familiarity with its effects,...

Electricity Basics When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance. These are the three basic building blocks required to manipulate and utilize electricity.

Electric charge refers to a fundamental property of matter that even physicists don’t totally understand. Electric current refers to the flow of the electric charge carried by electrons as they jump from atom to atom. An electric circuit is a closed loop made of conductors and other electrical ...

FUNDAMENTALS OF ELECTRICITY The technical term electricity is the property of certain particles to possess a force field which is neither gravitational nor nuclear. To understand what this means, we need to start simply. Everything, from water and air to rocks, plants and animals, is made up of minute particles called atoms.
