Do you know what is common between an electric eel, a bolt of lightning, and a glowing bulb? It is electricity ! An electric eel is a fish that makes its own electricity ,Lightning is spark of electricity in the air and bulb uses electricity to glow. Electricity is a form of energy produced by charges. These charges can be at rest or moving .Learn how these moving charges constitute current electricity.
Flow of free electrons (charges ) in a particular direction constitute an electric current or current electricity .Electric current is charge flowing per unit time through a conductor
Formula : Current = charge / time I = q / t
Learn about electric current and different symbols used in electric circuit. An electric circuit is closed path in which current flows. It comprises of electric components (cell or battery , bulb, switch, resistors ).Learn to make different electrical circuits and differentiate between open and closed circuits.
