This video lecture on the Del Operator (∇) and Basic Differential Calculus, an essential foundation topic of Engineering Physics, is designed for BTech 1st Year students. In this lecture, we introduce the del operator, its mathematical form, and its use in defining important vector operations like gradient, divergence, and curl.

You will clearly understand scalar and vector fields, partial derivatives, physical meaning of gradient, divergence, and curl, and why del operator is widely used in electrostatics, electromagnetism, and Maxwell’s equations. The explanation is conceptual, step-by-step, and exam-oriented, making it ideal for theory and viva preparation.

This lecture is especially useful for RGPV BTech 1st Year students, and is also relevant for AKTU, VTU, GTU, JNTU, SPPU, and other Indian engineering universities.

📘 This Engineering Physics Playlist Includes:

Del Operator & Vector Calculus
Gradient, Divergence & Curl
Electrostatics & Gauss Law
Stokes’ Theorem & Gauss Theorem
Maxwell’s Equations
Poynting Vector

🎯 This Video Is Helpful For:
