In this video, we develop a clear and intuitive understanding of the Wheatstone Bridge, suitable for Class 12 Physics – Current Electricity.
This is the 4th video in the Current Electricity series, where we go beyond memorizing formulas and focus on logical reasoning using Ohm’s Law and Kirchhoff’s Laws.
We first build the concept of Wheatstone bridge balance condition, and then solve a complete numerical problem step-by-step, including the calculation of galvanometer current.
📌 What you’ll learn in this video:
• Intuitive explanation of Wheatstone Bridge
• Logical derivation of balance condition (without heavy math)
• Application of Ohm’s Law and KVL
• Solved numerical with galvanometer resistance
• Exam-oriented approach for Class 12 & JEE/NEET basics
