Dielectrics

Science > Physics > Electrostatics > Dielectrics In this article, we shall study dielectric materials (dielectrics), their working and types. Dielectrics are non-conducting substances. In these materials, free-moving electrons are not present. Thus there is no question of the movement of charge. When the dielectric material is kept in an external electric field, a dipole […]
