Introduction
A dielectric material is any material that supports charge without conducting it to a significant degree. In principle all insulators are dielectric, although the capacity to support charge varies greatly between different insulators for reasons that will be examined in this TLP.
Dielectric materials are used in many applications, from simple electrical insulation to sensors and circuit components.
