blue_cristal Posted November 4, 2012 Share Posted November 4, 2012 If non-conductor materials like a rubber or glass rod have no free electrons then why they get charged with friction ? Is it due induction ( atomic polarization ) or something else ? Link to comment Share on other sites More sharing options...
