HOW IT WORKS: Electricity - Full Documentary

This educational HD video explains how electricity works and how its generated and distributed in the United States. In electrical engineering and physics, electricity is defined as a form of energy resulting from the existence of charged particles of electrons or protons in positive and negative forms that occurs naturally such as lightning or is produced by a generator and that is expressed in terms of the movement (flow) and interaction of electrons. Common forms of electricity in this movie are: static electricity, electromagnetic induction and electric current. Electrical current is either alternating current (AC) or direct current (DC). Electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity, charges produce electromagnetic fields which act on other charges. Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries but the most notable one is Benjamin Franklin and his flying kite experiment. Franklin was able to determine that lightning was a form of electrical discharge.
