Lecture
This lecture covers the electrical and magnetic properties of materials, including electrical conductivity, dielectric properties, and magnetic properties. It explains the importance of these properties in selecting materials for various applications and how materials must have specific mechanical characteristics. The lecture also delves into concepts such as electric charges, dipoles, and moments, as well as the functional properties of materials. Additionally, it discusses the Drude model, collisions on atoms, and the behavior of electrons in metals under electric fields. The presentation concludes with insights into electrical resistivity, thermal conductivity, and the behavior of insulators and semiconductors.
