Electric current: Definition Let us now define electric current

Electric Current Definition Let us now define electric current and also know about conductors and insulators. Electric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Electrons are minute particles that exist within the molecular structure of a substance. Sometimes, these electrons are tightly held, and other times they are loosely held. When electrons are loosely held by the nucleus, they are able to travel freely within the limits of ... These materials, generally called conductors, develop electric currents in them when an electric field is applied. If we consider solid conductors, then of course the atoms are tightly bound to each other so that the current is carried by the negatively charged electrons. Electric Current is a directed flow of electric charge or particles of electricity such as electrons, ions, or holes. It is measured in terms of the rate of flow of electric charge through a conductor. The particles that cause electric current to flow through a material are called charge carriers. Depending on the type of conductor, there are various types of charge carriers, such as electrons, holes, and ions. For example, in metals, electric current flows due to the movement of electrons ... The article explains the concept of electric current , including its definition, unit, formula, and examples. It covers the movement of charge carriers, the role of energy sources in generating current , conventional versus electron flow, and provides solved numerical examples to illustrate calculations related to electric current .
