Class 12 Semester 3 Physics chapter 2 | E ও V এর সম্পর্ক: E = -dV/dr | Potential Gradient

Class 12 Semester 3 Physics E and V relation in Bengali. Learn the relationship between Electric Field Intensity (E) and Electric Potential (V) with the formula E = -\frac{dV}{dr}.

In this quick and easy tutorial, we break down the connection between Vector (Electric Field) and Scalar (Electric Potential) quantities. We cover the full concept, the mathematical derivation, and what "Potential Gradient" (বিভবের নতিমাত্রা) actually means. We also solve important MCQs using both Differentiation and Integration methods to prepare you for your board exams, NEET, and JEE.
