UP Board Class 12 Physics – Electric Charges and Fields

“Electric Charges and Fields” is the first chapter of UP Board Class 12 Physics and forms the foundation of Electrostatics. This chapter introduces students to the basic concepts of electric charge, its properties, and the forces they exert on each other. Students learn about positive and negative charges, conservation of charge, quantisation of charge, and methods of charging such as friction, conduction, and induction.



A major focus of the chapter is Coulomb’s Law, which describes the force between two charges. The concept of electric field, electric field lines, and electric flux further helps students understand how charges interact in space. Gauss’s Law, one of the most powerful mathematical tools in electrostatics, is also introduced to simplify calculations of electric fields in symmetric situations.

This chapter builds analytical and mathematical skills through numerical problems and conceptual questions. Mastering Electric Charges and Fields is essential for understanding advanced topics like Electric Potential, Capacitance, and Electrostatic Applications in daily life.
