Electricity is one the most important sources of energy in the world

Electricity is one the most important sources of energy in the world. Almost every electronic device in every household depends on electricity. As such, mobile phones, computers, refrigerators, heaters, and bulbs and other major house appliances rely on electricity (Bloomfield 399). Electricity is a secondary source of energy. This source of energy has several primary sources, which includes water, oil, geothermal, nuclear, coal, and wind. The principle of electricity depends on the flow of electric charges (Bloomfield 362). Flowing electric charges are referred to as electric current.
