What is Electricity?

Electricity is a form of energy that is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are “lost” from an atom, the free movement of these electrons constitutes an electric current.

Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear, hydro power and other natural sources, which are called primary sources.

Sources of electricity are everywhere in the world. Worldwide, there is a range of energy resources available to generate electricity. These energy resources fall into two main categories, often called renewable and non-renewable energy resources. Each of these resources can be used as a source to generate electricity, which is a very useful way of transferring energy from one place to another such as to the home or to industry.

Like as in Cambodia, we can call the Electricité Du Cambodge (EDC) to generate, transmit and distribute the electricity in Phnom Penh and provinces throughout Cambodia, and to be attached to the Ministry of Energy, to be restructured under the Ministry of Industry, Mines and Energy (MIME) and to be responsible for the development, management and operation of the power system.

Structure Of The Industry Right now the world is always developed and grows up every day, and the electricity is also that as few idea below:

Modern electric utilities have three major organizational components: generation (power plants), transmission (high-voltage bulk power between utilities), and distribution (low-voltage power to ultimate consumers). Modern electric utilities not only produce the power they need for their consumers but also pool and coordinate excess electricity with other utilities.

Dangers And Liabilities Electricity, especially at high voltages or high currents, is a dangerous commodity. Faulty wiring, power lines that are close to trees and buildings, and inadequate warning signs and fences around transformer stations and over buried electrical cables can subject an individual to electric shock or even electrocution. Because of the ultrahazardous nature of providing electric power, states have many statutes and regulations in place to protect the public from electric shock.
