Lecture
This lecture covers the basics of electrostatics, including electric charges, Coulomb's force, electric field, and the principle of superposition. The instructor introduces the concept of electric potential, conductors, and demonstrates experiments related to Faraday's cage. The lecture also explores the calculation of electric potential for a dipole, the concept of equipotentials, and the behavior of electric forces in different scenarios. Additionally, the lecture delves into the principles of electric potential energy, voltage, and the concept of equipotential lines. The instructor concludes with a demonstration of the Faraday cage and the importance of lightning protection.
