Capacitors and Capacitance of Parallel Plate Capacitor| Electric Potential & Capacitor| Physics 12 #FederalBoard #ModelTownHumak #EducationalChannel #siranjumteaches #nationalbookfoundation 📘 In this lecture, we discuss *Capacitors and the Capacitance of a Parallel Plate Capacitor* as covered in Physics Class 12 by the National Book Foundation (NBF). 🔋 A capacitor is a device used to store electric charge and energy. This lecture introduces: • What is a capacitor? • How capacitors work • Types of capacitors (focus on parallel plate capacitor) 📐 The formula for the capacitance of a parallel plate capacitor is derived as: C = ε₀ A / d Where: C = capacitance ε₀ = permittivity of free space A = area of plates d = distance between plates 📊 The lecture also covers: • SI unit of capacitance (Farad) • Factors affecting capacitance • Effect of dielectric materials on capacitance • Physical significance and practical use of capacitors 💡 This concept is widely used in electronics, timing circuits, energy storage, and filtering AC signals. 🎓 Ideal for FSC Part 2 students preparing for board exams or strengthening basic concepts in electrostatics. 📗 Book: Physics Class 12 – National Book Foundation 📍 Lecture 4 | Chapter: Electric Potential & Capacitor 👨‍🏫 Instructor: Sir Anjum Teaches 📌 Like, Share & Subscribe to stay updated with more conceptual videos! #Capacitor #ParallelPlateCapacitor #Physics12 #Class12Physics #ElectricPotential #FSCPhysics #CapacitanceFormula #CapacitorConcepts #NBFPhysics #SirAnjumTeaches #Electrostatics
