Etymology

The term 'dielectric' comes from the Greek words 'dia' meaning 'through' and 'electric' related to electricity. It was first introduced in the 19th century to describe materials that exhibit insulating properties in the presence of an electric field. Dielectrics play a crucial role in various fields such as electronics, telecommunications, and power systems, where their ability to store and transmit electrical energy efficiently is utilized.
