What does the Electron Flow Concept describe?

The Electron Flow Concept primarily describes the movement of electrons in a circuit, which is conventionally understood as flowing from negative to positive. This concept is grounded in the nature of electricity and how electrons, which carry a negative charge, respond to electric fields. When a voltage is applied in a circuit, electrons are repelled from the negative terminal (the source of excess electrons) and attracted towards the positive terminal (where there is a deficit of electrons).

Understanding this flow is crucial in electronics, as it lays the foundation for analyzing circuit behavior, including current flow, voltage levels, and how various components interact within an electrical system. The conventional direction of current, which is from positive to negative, stems from historical conventions established before the electron was understood, but the true movement of charge carriers (electrons) aligns with the negative to positive direction.

This foundational knowledge aids technicians and engineers in troubleshooting and designing circuits, ensuring proper function and safety across various applications.
