What is Electrical Energy?

Electrical energy is the occurrence and current of an electric charge. The power portion of electricity is start in a range of phenomena such as static electricity, electromagnetic fields and lightning. Humans have start the ability to attach these phenomena and store the electrical accuse for later use. The concept of electrical energy is clear using a variety of dissimilar terminologies such as charge, current and potential.

Electrical energy is the result of the interface of subatomic particles with electromagnetic force. Within an atom, electrons and protons create a charge. This charge can be transferred among bodies using direct contact with a conductive object like a wire.

The current refers to the faction of the charge. With direct current, this occurs when the electricity is stored in a battery and travels in one route out of the battery. Alternating current occurs when the current changes direction constantly within an electrical system. The alternating current type is usually used to power bigger objects such as residences and buildings.

Electrical potential is necessary to the range and power of electric energy. When an electric charge exists within an object, a force is exerted from its electrical field. This accelerates the object in a direction each towards or away from the charge, depending on the electromagnetic division generally, positively-charged electricity pushes the object away, while negatively-charged electricity pulls the object towards the field.

Electrical energy can be generated using a diversity of means. The flaming of fossil fuels or the heat from nuclear reactions produces vapor that powers a generator which, in turn, creates electricity. Otherwise, kinetic energy extracted from either wind or water can power analogous generators. All of these methods require a transformer that modifies the electrical energy into a higher voltage with lower current. Different methods of storing this energy include capacitors and batteries.

The oldest recognized civilization that understood electrical energy were the antique Egyptians. Texts from 2750 BC refer to the “Thunderer of the Nile” and define the shocks of electric fish. Knowledge and study of the fish continued through the millennia with Greek, Roman and Arab scholars. Pliny the Elder and Scribonius Largus researched the numbing effects of electric shocks. In addition, a number of Arab scientists firm the same phenomena caused lightning.

Until 1600, much of the understanding of electricity as an energy source was purely intellectual. William Gilbert, an English physician, studied electricity and magnetism. A number of other researchers continued the study including Otto von Guericke, Robert Boyle and Benjamin Franklin. By the 1800s, scientists such as Alessandro Volta had identified a way to attach electricity into a battery format.
