Class 12 Physics Chapter 03 Temperature Dependence of Resistivity for conductors & semiconductors

📌 Chapter 3: Current Electricity | Class 12 Physics 🎯 Topic Covered: Mobility of Charge Carriers & Temperature Dependence of Resistivity 📚 Syllabus Covered: CBSE | JEE | NEET | UP Board 🧠 In this video, we dive deep into two very important concepts from Chapter 3 – Current Electricity: 🔹 1. Mobility of Charge Carriers (μ): • What is mobility of charge carriers? • Derivation of relation: μ = eτ/m • How mobility affects conductivity • Factors influencing mobility in conductors and semiconductors • Comparison between electron and hole mobility • Real-life significance in semiconductors and electronic circuits 🔹 2. Temperature Dependence of Resistivity: 🔸 In Conductors: • Explanation of why resistivity increases with temperature • Role of lattice vibrations and scattering • Linear temperature-resistivity relation: ρ = ρ₀(1 + αT) • Graphical explanation with slope and intercept 🔸 In Semiconductors: • Why resistivity decreases with temperature • Concept of thermal excitation of electrons • Behavior of intrinsic and extrinsic semiconductors • Real-life application: Temperature sensors, thermistors, etc. 💡 Concepts Explained with: • Real-life examples • NCERT + competitive level insights • Graphs and visual animations for better understanding • Useful tips for exams 🎥 Whether you’re preparing for boards or competitive exams like NEET & JEE, this video simplifies the concepts and makes them easy to retain. ⸻ 📌 Don’t forget to LIKE 👍 | SHARE 🔁 | SUBSCRIBE 🔔 📺 Channel: MILESTONE GURUCOOL – Your destination for Class 10, 11, 12, NEET & JEE learning! 📌 #PhysicsClass12 #CurrentElectricity #MobilityOfChargeCarriers #TemperatureDependence #Semiconductors #Resistivity #JEEPhysics #NEETPhysics #CBSEPhysics #MilestoneGurucool
