In which direction do electrons flow?

Electrons flow from negative to positive due to their negative charge. This movement happens in electrical circuits, where the power source creates a difference in electric potential between two points. The negative terminal has an excess of electrons, which creates a higher concentration of negative charge. Electrons are then attracted to the positive terminal, which has a deficiency of electrons.

This flow is fundamental to understanding electrical circuits and is rooted in the behavior of electrons at the atomic level. In the context of electrical engineering and physics, it is essential to recognize that while conventional current is described as flowing from positive to negative, the actual movement of electrons occurs in the opposite direction. Understanding this concept is critical for anyone studying electrology, laser, and IPL technologies, as it lays the groundwork for comprehending how electrical devices operate and how therapies using electrical currents work.
