Class 12 Physics chapter "Electric field and charge" Theory Notes - CBSE & MPBOARD [NCERT Based] 2026
Chapter Summary: Electric Charges and Fields (Class 12 Physics) This comprehensive study note covers the foundational principles of Electrostatics. It is structured to help students grasp complex concepts through logical derivation and visual mapping, making it ideal for both board exams and competitive entrance tests. Core Topics Covered Properties of Charge: Quantization, conservation, and additivity. Coulomb’s Law: Force between point charges in vacuum and medium, including vector form. Electric Field (E): Field intensity due to point charges and systems of charges. Electric Dipole: Detailed derivations for Electric Field on Axial and Equatorial lines, and Torque in a uniform field. Electric Flux (Φ): Conceptual breakdown and mathematical definition. Gauss’s Law & Applications: * Field due to an infinitely long straight wire. Field due to a uniformly charged infinite plane sheet. Field due to a uniformly charged thin spherical shell.
