Parallel Plates and Capacitance
Learning Time: 4-12 hours
Content: Parallel plates and capacitance is a subject that examines the structure and behavior of capacitors that store electric charges. This subject covers the definition of a parallel plate capacitor, capacitance calculation (C = ε₀A/d), the dielectric effect, energy storage, and practical applications. TYT focuses on basic capacitance and charge, while AYT focuses on dielectrics and complex circuits. The current 2025 curriculum also covers energy storage technologies and electronic devices. Learning this topic lays the foundation for electrical circuits.
