Electrical basics

In order to understand even the simplest concepts of electronics, you must first understand what electricity is. After all, the whole purpose of electronics is to get electricity to do useful and interesting things. The concept of electricity is both familiar and mysterious.

We all know what electricity is, or at least have . Basic electrical terms and concepts - current, voltage, resistance, charge, power, efficiency.

This electric current takes the form of free electrons that transfer from one atom to the next.

There are three primary electrical parameters: the volt, the ampere and the ohm.

The source of this force has been given the name charge. A very noticeable thing about electric force is that it is large, far greater than the force of gravity. Unlike gravity, however , there are . Understanding Basic Electrical Theory. No single discovery has affected our lives , our culture and our survival more than electricity.

For an example, imagine where the medical field would be without electricity and in that sense how . 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. At first, these concepts can be difficult to understand because we cannot . In order for the Source-and-Destination scheme to work, both would have to have an infinite capacity for electrons in order to sustain a . Electricity basics explained without using complicated physics.

The right wire connector, used correctly, can help DIYers take on electrical jobssafely. The foundation of electrical theory and the application of its principles. Learn from our online electronics tutorials. This module shows how electrical circuits can be damaged by fire, discusses how electrical arcs occur, defines and describes the . To begin to explain what electricity is we need to zoom way in, beyond the matter and molecules, to the atoms that make up everything we interact with in life. This tutorial builds on some basic understanding of physics, force, energy, atoms, and fields in particular.

How to test and understand basic electrical circuits. As you can see from the illustration, the features are grouped together according to types of activity. After you finish this guide, you can access the linked Help commands in each .
