This course is for the students of 12th standard of the CBSE board. This course covers various topics in ELECTRIC CHARGES AND FIELDS. Here we discuss about the history of discovery of electric charge in Greece.Acquiring positive and negative charge by the glass rods and ebonite rods on rubbing them with silk cloth and fur respectively; Attraction and repulsion of glass rods and ebonite rods because of the charges present on these rods; about the device to detect the charges; conductors and insulators; Basic properties of electric charge such as additivity of charges, conservation of charges and quantisation of charges; the value of basic unit of charge ; Coulomb's law and definition for Coulomb; Forces between multiple charges; Electric field and Electric field due to a system of charges; Physical significance of electric field;Electric field lines;Electric flux;Electric dipole;The field of an electric dipole; Physical significance of dipoles;Dipole in uniform external field;Continous charge distribution; Gauss' law and its applications
