Free electrons are electrons that are not bound to an atom and can move freely through a material, playing a crucial role in electrical conductivity. They are fundamental in understanding the behavior of metals and semiconductors, as they facilitate the flow of electric current when subjected to an electric field.

Electrical conductivity is a measure of a material's ability to allow the flow of an electric current, which is determined by the availability and mobility of charge carriers such as electrons or ions. It is a critical property in determining the suitability of materials for applications in electronics, energy transmission, and electrochemical processes.

An electric field is a vector field around a charged particle that represents the force exerted on other charges placed within the field. The strength and direction of the electric field are determined by the magnitude and sign of the charge, as well as the distance from the charge.
