Electrostatics
Learning Time: 4-12 hours
Content: Electrostatics is the study of the behavior of electric charges at rest. This subject covers the nature of charges (positive, negative), Coulomb’s Law, electric fields, potential differences, and charge distribution. The TYT focuses on fundamental charge interactions, while the AYT focuses on the mathematical model of the electric field. The current 2025 curriculum also covers electrostatic technologies (electrostatic precipitators) and their environmental applications. Learning this topic provides the foundation for understanding electrical phenomena.
