What is Electrical Energy?

Electrical energy is the presence and flow of an electrical charge. The energy of the electricity that is found in a variety of phenomena such as static electricity, electromagnetic fields and lightning. People have the ability to use these phenomena and store the electrical charge for later use found. The concept of electric energy is defined using a variety of different terminologies such as charge, current and potential.

Electrical energy is the result of the interaction of subatomic particles with electromagnetic force. to create within an atom, electron and proton charges. This fee can be transferred between devices with direct contact with a conductive material such as a wire.

The date refers to the movement of cargo. With DC, this occurs when the power is stored in a battery and in a direction from the battery. AC occurs when the current changes direction again within an electrical system. The alternating current form is typically used to power larger objects such as houses and buildings.

Electric potential is essential for the selection and the power of the electrical energy. When an electrical charge is present in an object, a force is exerted by its electric field. This speeds up the object in a direction toward or away from the fee, depending on the polarization of electromagnetic. In general, positive charged current pushes the object away, while negatively charged current, the object moves on the field.

Electrical energy may be using a variety of means. The burning of fossil fuels or the heat generated from nuclear reactions steam that drives a generator which in turn creates electricity. Otherwise extracts kinetic energy from wind or water current similar generators. All these methods require a transformer that changes the electrical energy to a higher voltage with lower current. Various methods of storing this energy are capacitors and batteries.


The oldest known civilization, the electric energy were understood by the ancient Egyptians. Texts from 2750 BC refer to the "Thunderer of the Nile" and define the shocks of electric fish. Knowledge and study of fish on through the thousands of Greek, Roman and Arab scholars. Pliny the Elder and Scribonius Largus explores the numbing effect of electric shocks. In addition, a number of Arab scientists determined the same phenomena caused flash.


Until 1600, a large part of the understanding of power as an energy source purely intellectual. William Gilbert, an English physician, studied electricity and magnetism. A number of other researchers used the study of Otto von Guericke, Robert Boyle and Benjamin Franklin. By the 1800s, scientists such as Alessandro Volta had identified a way to use electricity in a battery format. This has been perfected over the years by engineers such as Nikola Tesla and Thomas Edison.
