Dielectrics and Polarisation
Dielectrics
Dielectrics are non-conducting substances. In contrast to conductors, they have no or the negligible number of charge carriers. In a dielectric, free movement of...
Electrostatics of Conductors
Electrostatics of Conductors
Conductors contain mobile charge carriers. In metallic conductors, these charge carriers are electrons. In a metal, the outer (valence) electrons part away...
