electric current definition

Electric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example). In conductors or semiconductors, electric current is conducted by the tiny particles. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. Electric current definition The flow of electric charge carriers in a conductor or semiconductor is called an electric current. In other media, any stream of charged objects (ions, for example) may constitute an electric current. So, in metals where the charge carriers (electrons) are negative, conventional current is in the opposite direction to the overall electron movement. https://en.thefreedictionary.com/electric+current, Here, without the use of a battery, with no more, What remained to be done was to construct such a machine and find out how the, He was a third-generation specialist in the nature of speech, and he knew that for the transmission of spoken words there must be "a pulsatory action of the, I tested the electric signals from the gatling platform to the cave, and made sure that they were all right; I tested and retested those which commanded the fences -- these were signals whereby I could break and renew the, There was no doubt but that the grasshopper controlled an, It would be the safest possible place--so long as one was not in the line of the, Let the press strike off millions of copies; let the, The National Electric Power Regulatory Authority (NEPRA) has launched inquiry against K-Electric and has constituted inquiry committee to probe into the casualties caused due to, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, NEPRA orders inquiry against K-Electric on casualties caused by electric currents, Electric Consumers Protection Act of 1986, Electric Continuously Variable Transmission. Discussion definitions current. Electric current definition, the time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes. In metallic solids, electric charge flows by means of electrons, from lower to higher electrical potential.

When it comes in the form of lightning, this force can set fire to foliage and damage buildings.To prevent lightning damage to buildings in areas prone to lightning storms, building owners often install devices called lightning rods that attract the lightning charge to a high metal rod, which redirects and dispels the current underground. Despite referring to many different things, the word current is often used by itself instead of the longer, more formal "electric current". Using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. Electric Current Definition. Define electric current. Electrical current is the flow rate of electric charge in electric field, usually in electrical circuit. Electric Current Definition: Electric current is defined as the rate of flow of negative charges of the conductor.In other words, the continuous flow of electrons in an electric circuit is called an electric current.The conducting material consists a large number of free electrons which move from one atom to the other at random. Electric current can cause fire. Electric current definition is - a movement of positive or negative electric particles (such as electrons) accompanied by such observable effects as the production of heat, of a … Electric Cooperatives of South Carolina, Inc. Electric Diesel Climatisation Maintenance. The adjective "electric" is implied by the context of the situation being described. Electric current, any movement of electric charge carriers such as electrons, protons, ions, or holes. An electric current is a flow of particles (electrons) flowing through wires and components. n another name for current8 Noun 1. electric current - a flow of electricity through a conductor; "the current was measured in amperes" current … It is the rate of flow of charge.If the electric charge flows through a conductor, we say that there is an electric current in the conductor.In the circuits using … The electrical current is measured in ampere (amp) unit. Electric current definition. To gain a deeper understanding of what an electric current is and how it behaves in a conductor, we can use the water pipe analogy of electricity.Certainly, there are some limitations but they serve as a very basic illustration of current and current flow. Visualizing Electric Current. In conductors where the charge carriers are positive, conventional current is in the same direction as the charge carriers. See more. electric current synonyms, electric current pronunciation, electric current translation, English dictionary definition of electric current. To provide a definition of current independent of the type of charge carriers, conventional current is defined as moving in the same direction as the positive charge flow. Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Electric current calculation.
