Electrostatics Notes for JEE

Subtopics in Electrostatics

• Electric charges: conservation of charge, Coulomb's law forces between two point charges, forces between multiple charges, superposition principle and continuous charge distribution
• Electric field: electric field due to a point charge, electric field lines, electric dipole, electric field due to a dipole, torque on a dipole in a uniform electric field
• Electric flux, Gauss's law and its applications to find field due to infinitely long uniformly charged straight wire, uniformly charged infinite plane sheet and uniformly charged thin spherical shell
• Electric potential and its calculation for a point charge, electric dipole and system of charges
• Potential difference, equipotential surfaces, electrical potential energy of a system of two point charges and of electric dipole in an electrostatic field
• Conductors and insulators, dielectrics and electric polarization
• Capacitors and capacitance, the combination of capacitors in series and parallel
• Capacitance of a parallel plate capacitor with and without dielectric medium between the plates, energy stored in a capacitor
