Dielectrics & Conductors in Electric Field | Electrostatics | Part 8 | Class 12 Physics

Описание: Dielectrics & Conductors in Electric Field | Electrostatics | Part 8 | Class 12 Physics
In this video, we dive deep into the behavior of Conductors and Dielectrics when placed in an external Electric Field. Real life me charges vacuum me nahi, materials ke andar hote hain!
Aaj hum samjhenge ki kyu Conductor ke andar Electric Field ZERO hoti hai (Shielding) aur kaise Dielectrics field ko reduce karte hain (Polarisation). We will also cover the most important derivation for Board Exams and a step-by-step strategy to solve numericals.

📝 In this Lecture, you will learn:
The fundamental difference between Conductors and Dielectrics.
Derivation of Induced Charge Density (Board Exam Favorite!).
The "Material ID Checklist" to solve any exam problem.
Common mistakes students make with Dielectric Constant (K) and Strength.
