Introduction to Electricity and Magnetism

This lecture introduces the fundamental concepts of electricity and magnetism, starting from ancient observations to the development of Maxwell's equations in the 19th century. It covers the impact of electromagnetism on technology, the nature of light, and the quantization of electric charge. The lecture also explains the properties of insulators and conductors, charging mechanisms, and Coulomb's law. Additionally, it discusses point charges, charge densities, and the superposition principle in electric fields.
