Lecture
This lecture introduces the concept of electric field, starting with the fundamental idea of electric charge and the role of electrons. The instructor explains how charges create an electric field, the relationship between force and charge, and the concept of electric potential. The lecture also covers the homogeneity of electric fields in capacitors, the calculation of electric field strength, and the connection between voltage and electric field. Through examples and explanations, students learn how to analyze and understand electric fields in different scenarios.
