📘 Description:

Welcome to today’s Physics class with VK Sir at JRS Academy!
In this lecture, we focus on one of the most repeated topics from Units & Dimensions — the Dimensional Formula of Planck’s Constant (h) and Angular Momentum (J or L).

This question appears frequently in TGT, PGT, LT, B.Ed, CTET, UPTET, Super TET, and other competitive Physics examinations, making it very important for scoring full marks.

You will learn:
✔ How to derive dimensions from physical definitions
✔ Relation of Joule, angular momentum, and momentum dimensions
✔ Shortcut tricks for remembering standard dimensional formulas
✔ Actual exam-based MCQ with correct method and explanation

👉 Watch till the end for theory + derivation + correct option + PYQ logic.
