The Electronic Theory of Frictional Electricity explains how objects become charged through friction. When two materials come into contact and then separate, electrons transfer due to differences in electron affinity. This transfer causes one material to become negatively charged and the other positively charged. Key concepts include electric charges, conductors, insulators, and Coulomb's Law, which quantifies the force between charges. The theory also covers electrostatic induction, where a charged object induces a charge in a nearby neutral object. This foundational theory is essential for understanding electrostatics and is crucial for IIT and NEET exam preparation.
