The free electrons in practical dielectrics are due to ________(a) There are no free electrons(b) Conductors(c) Impurities(d) Displacement currents

Answer» The correct option is (c) Impurities

Easy explanation: Ideally, dielectrics are insulators and do not contain any free electrons. But no dielectric is a perfect dielectric, hence the free electrons are due to impurities present in each dielectric.
