Answer to Question #305712 in Electricity and Magnetism for Himanshu

Question

a dielectric object is placed in an electric field.the object becomes polarised and a large number of atomic inmolicular dipole in the object align in the direction of the applied electric field.drive an expression for the electric potential due to this polarised dielectric at a point outside the dielectric

Answer 1

Answer

According to physics, When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. Instead, electric polarization occurs.
