About this unit
Coulomb’s law; Electric field and potential. Electrical potential energy of a system of point charges and of electrical dipoles in a uniform electrostatic field. Electric field lines; Flux of electric field. Gauss’s law and its application in simple cases, such as, to find field due to infinitely long straight wire, uniformly charged infinite plane sheet and uniformly charged thin spherical shell. Capacitance, Parallel plate capacitor with and without dielectrics. Capacitors in series and parallel, Energy stored in a capacitor.
