WebElectric 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. In alternating current the motion of the electric charges is periodically reversed; in direct current it is not. ... which is defined as a flow of one coulomb of charge per second, or 6.2 × ... WebJul 26, 2024 · Current is the rate of flow of charge through a surface (often an imaginary surface). If positive charge is passing through the surface from side A to side B, we say that there is a current in the direction AB. This definition or convention enables us to write, without any minus sign, I A B = Δ Q A B Δ t
