Dielectric Materials

Dielectric is a material in which energy can be accumulated. Ideally, it  is  a non-conductor  of  electric  charge  like  insulators, but  an  efficient   supporter  of  electrostatic  fields. The distinction between the insulators and dielectrics and dielectrics lies in the application to which each is employed; Insulating materials are used to resist the flow of current in a certain direction, while the dielectric materials are used to accumulate electrical energy. "Materials which are electrical sustained with a least dissipation of power can be termed as dielectric materials". This property is helpful in capacitors, particularly at radio frequencies. Dielectric materials are also required in the construction of radio frequency transmissions lines.
