👉 Pielike is a term used in physics and engineering to describe a material that has an electric field that is proportional to its surface charge density. It is a type of permittivity, where the electric field E is directly proportional to the surface charge density σ. In other words, if the surface charge density is increased, then the electric field will increase proportionally. This property is useful in materials science and engineering for designing materials with high conductivity and low resistance. Pielike materials are often
