1 Reviews on electrastatics Electric charges: Two types, positive and negative. Like charges repel, unlike charges attract. Charges conserve. The force between two point charges is governed by Coulomb’s Law. Electric charges generate electric fields. Electric field exerts force on charges inside it. Charges inside an electric field has potential energy U . This potential energy equals the work the field does to the charge to move it outside of the field. Electric field has energy with an energy density of Electric field generated by point charge can be calculated using Coulomb’s Law. Electric field generated in three special cases can be calculated using Gauss’ Law. There is no electric field inside conductors: Faraday Cage.
