the Drude model

The Drude model is a theoretical framework that describes how electrical conduction occurs in metals. It likens electrons in a metal to a gas of particles, where they move freely between fixed positively charged atomic cores. When an electric field is applied, these electrons accelerate, leading to an electric current. The model helps explain properties like conductivity and temperature effects on resistance. Although it oversimplifies some aspects of electron behavior and interactions, it provides a useful starting point for understanding how metals conduct electricity.
