WebElectrical. Current 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 measuring current. It expresses the quantity of electrons (sometimes called "electrical charge") flowing past a point in a circuit over a given time. WebIn practice, electric current is not calculated using Equation 1 because you cannot directly measure coulombs in charge. As you will learn, there are far more practical ways to calculate current. Two Theories: Conventional Current and Electron Flow. There are two theories that describe electric current, and you will come across both in practice. WebMar 20, 2024 · Electric current and charged objects involve the separation of some of the negative charge of neutral atoms. Current in metal wires consists of a drift of electrons of which one or two from each atom are more loosely bound than the rest. cundalls facebook
