The primary difference between an insulator and a dielectric lies in their applications and properties. An insulator is a material that resists the flow of electric current, while a dielectric is specifically characterized by its permittivity, making it essential in applications like capacitors and transmission lines. Notably, some materials, such as water, can serve as dielectrics despite being poor insulators. Understanding these distinctions is crucial for selecting appropriate materials in electrical engineering.
