Description

This lecture covers the fundamental properties of electric charges, including their quantification and conservation. It explains the concept of ions, conductors, and insulators, detailing the movement of electric charges in different materials. The lecture also delves into semiconductors, electric power, and the measurement of electric current. Additionally, it discusses the direction of current flow, the role of ammeters, and the perception threshold of electric currents. The presentation concludes with an exploration of drift speed and the factors influencing the velocity of electric charges in a conductor.
