[latexpage]Motion is a relative concept. You are sitting on a train. An object on trains seems to be at rest from your perspective but it is in motion from the person standing on the ground. So it is tied to a particular frame of reference chosen by observer.Now Different observer may use the different frame […]

This article is about Maxwell’s Equations. 1. Integral Form of Gauss’s Law Under this heading, I’ll cover ” Gauss’s law for electric fields ” which is among one of Maxwell’s equations. In this article, I’ll try to cover the Integral form of Gauss’s Law.Gauss’s law for electric fields as we all know deals with the

In this article learn about what is Gradient of a scalar field and its physical significance. We have also written an article on scalar and vector fields which is the topic you must learn before doing this topic. The gradient of a scalar field Let us consider a metal bar whose temperature varies from point

In this article, learn what are Scalar and Vector fields. We know that many physical quantities like temperature, electric or gravitational field, etc. have different values at different points in space, for example, the electric field of a point charge is large near the charge and it decreases as we got farther away from the

Fourier series is an expansion of a periodic function of period $2\pi$ which is representation of a function in a series of sine or cosine such as $f(x)=a_{0}+\sum_{n=1}^{\infty }a_{n}cos(nx)+\sum_{n=1}^{\infty }b_{n}sin(nx)$ where $a_{0}$ , $a_{n}$ and $b_{n}$ are constants and are known as fourier coefficients. In applying fourier theorem for analysis of an complex periodic function , given function must satisfy following condition (i) It

This article is about the levels of teaching. We have three levels of teaching that are 1. memory level of teaching 2. understanding level 3. reflective level. In this article, we will learn in detail about different teaching levels one by one. For all the notes on subject teaching and Learning for B.Ed. please visit
