Relation Between Current Density & Electric Field Intensity || Supper Conductor & Perfect Conductor

Relation Between Current Density & Electric Field Intensity || Superconductor & Perfect Conductor || Class 11/12 Physics || NEB || Edusansaar 📌 About this video: In this video, we explain the relation between current density (J) and electric field intensity (E) using Ohm’s law in microscopic form, and clearly differentiate between a perfect conductor and a superconductor, as per the NEB Class 11/12 Physics syllabus. 🔍 Topics Covered: ✅ What is current density (J)? ✅ What is electric field intensity (E)? ✅ Microscopic form of Ohm’s law ✅ Electrical conductivity (σ) and resistivity (ρ) ✅ Behavior of J–E relation in different materials ✅ Perfect conductor:   🔹 Zero resistivity (theoretical)   🔹 No energy loss   🔹 Temperature independent ✅ Superconductor:   🔹 Zero resistivity below critical temperature   🔹 Meissner effect (expulsion of magnetic field)   🔹 Practical applications ✅ Key differences between a perfect conductor and a superconductor (NEB exam-important) 🎯 Useful for: ✔️ Class 12 NEB Physics students ✔️ Board exam & entrance preparation ✔️ Conceptual questions and short answers ✔️ Modern physics & current electricity topics 📚 Related Videos: ▶️ Drift Velocity & Mobility ▶️ Ohm’s Law (Microscopic Form) ▶️ Meissner Effect 🔔 Subscribe to Edusansaar for NEB-focused Physics: ▶️ [YouTube Channel Link] 📌 #CurrentDensity #ElectricField #Superconductor #PerfectConductor #Class12Physics #NEB #Edusansaar #PhysicsInNepali #CurrentDensity #ElectricFieldIntensity #OhmsLawMicroscopic #SuperConductor #PerfectConductor #Electromagnetism #Class12Physics #NEBPhysics #PhysicsInNepali #PhysicsTutorial #ElectricCurrent #PhysicsForStudents #STEMEducation #ScienceYouTube #PhysicsShorts #LearnPhysics #SolidStatePhysics #ElectricalConductivity #PhysicsMadeEasy #Edusansaar
