Lecture
This lecture discusses the behavior of an electric dipole in external electric fields, focusing on the force, torque, and potential energy calculations. It also covers the alignment of electric dipoles, thermal agitation, and electrical potential energy. The lecture further explores the electric field inside dielectric insulators and infinite metallic planes, emphasizing the impact of polarization on the material. Additionally, it delves into the screening of electric fields in dielectrics and the concept of relative permittivity. The instructor highlights the importance of understanding the interaction between dipoles and fields for various applications.
