WebCurrent is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for … WebElectricity is a form of energy. It is the phenomenon that describes the flow of charged particles (particularly electrons) from one place to another. The SI base unit of electric current is amperes (A). Conventional current is described as the flow of positive charge from the cell’s positive terminal to its negative terminal.
WebDefinition: 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.
