We explore why Maxwell had to correct Ampere's Law to save the principle of continuity and how this led to the discovery of Electromagnetic Waves. If you are a NEET or JEE aspirant, understanding the difference between Conduction Current (Ic) and Displacement Current (Id) is crucial for solving Capacitor and EM Wave problems accurately. 🔥 What You Will Learn in This Video: The "Broken" Circuit: Why Ampere’s Law (∮ B·dl = μ₀I) fails when applied to the gap between capacitor plates. Maxwell’s Genius Fix: How a changing Electric Field behaves exactly like a current. The Real Mechanism: It’s not electrons crossing the gap! It is the time-varying Electric Flux (dΦ/dt) and dielectric polarization. Continuity Equation: Proving that Conduction Current in the wire equals Displacement Current in the gap (Ic = Id). Modified Ampere-Maxwell Law: The complete equation that rules Electromagnetism. 📝 Key Formulas Covered: Displacement Current: Id = ε₀ (dΦE / dt) Modified Ampere’s Law: ∮ B·dl = μ₀ (Ic + Id) Current Continuity: Ic (wire) = Id (gap) 💡 Important Concept: Displacement Current is NOT a flow of charges. It is caused by the rate of change of Electric Flux. This ensures that magnetic fields are created even in a vacuum or dielectric where no physical charge is flowing. 🚀 Topics Covered: 0:00 - Introduction: The Flaw in Ampere’s Law 2:35 - Why Conduction Current fails in a Capacitor 11:49 - What is Displacement Current?
