Introduction to EM Theory, Lecture notes of Physics

An introduction to dielectric materials and capacitance. It explains the behavior of non-conducting materials in electric fields and the concept of dielectric constant. The document also discusses the polarization of dielectric materials and the types of dielectrics. It further explains the behavior of polar and non-polar dielectrics in electric fields and the concept of dielectric constant. The document can be useful for students studying electrical engineering or physics.
