👉 Courants, also known as fluxes or current flows, are a type of physical quantity that describe the movement of electric charges in an electrical system. They are fundamental to understanding how currents and voltage can affect the behavior of electrical circuits and systems. In simple terms, a courant is a flow of charge through a circuit. It's like water flowing through pipes, but it's moving from one place to another at different speeds. The speed at which charges move in a circuit determines the type of
