NEET EXAM INFORMATION
LENS MAKER FORMULA
( CLASS-12TH )
LENS FORMULA ( CLASS-12TH)
Welcome to Satish Goyal Physics Classes, New Delhi!
In this detailed lecture, Satish Goyal Sir explains the concept of Electrostatic Shielding — one of the most fascinating and practically important topics in Electrostatics from the Class 12 Physics syllabus.
Electrostatic Shielding is the phenomenon of protecting a region from external electric fields using a conducting enclosure. This principle is widely used in real-life applications — from airplanes, cars, and laboratories to electronic circuits that need protection from external charges.
In this lecture, you will learn:
🔹 What is Electrostatic Shielding?
🔹 Why do electric fields not penetrate a conductor?
🔹 How conductors provide protection from external electric fields?
🔹 Real-life examples: protection in airplanes, cars, and communication cables
🔹 Concept of Faraday Cage and its applications
🔹 Relationship between induced charge and shielding effect
🔹 Numerical examples and conceptual questions from NCERT and JEE/NEET level
This video will help students of Class 12 CBSE, ICSE, and State Boards, as well as JEE Main, JEE Advanced, and NEET aspirants, to clearly understand how electrostatic shielding works and where it is applied in daily life.
In this lecture, Satish Goyal Sir explains the concept of Permeability, a key topic in Class 12 Physics and Magnetism. Learn about magnetic permeability, relative permeability, and how materials influence magnetic fields. This video covers concepts, examples, and applications essential for CBSE, JEE, and NEET preparation. Strengthen your understanding with clear explanations and practical examples.
In this lecture, Satish Goyal Sir explains the concept of Permittivity, an important topic in Class 12 Physics and Electrostatics.
