By Vishal Singh Chandel
This e-book is an introductory direction intended for the scholars of B.Tech Semester II. The salient gains of the booklet are : various target difficulties in addition to brief questions based on new development of exam. New subject matters e.g. nanotechnology, ultrasonic and superconductivity have been lately brought within the syllabus and feature been lined with enough info within the e-book. representation and figures to give an explanation for the complicated techniques. Discussions at the themes that are even if now not the a part of UPTU syllabus are of extreme value for the coherence of the problem.

Electromagnetism is prime to the entire of electric and digital engineering. It presents the foundation for realizing the makes use of of electrical energy and for the layout of the entire spectrum of units from the most important turbo-alternators to the smallest microcircuits. This topic is an important a part of the schooling of digital engineers.
James Clerk Maxwell's (1831-1879) contributions to twentieth-century technology and know-how - specifically, the displacement present and the electromagnetic concept of sunshine - are one of the such a lot dazzling ideas within the historical past of physics, however the technical complexities and thematic subtleties of his paintings were tricky to resolve.

Goes to infinity as y goes to infinity. Divergent for y~oo. Hence this is physically acceptable only when the series is terminated after certain r. we can do this by setting. Al =0 (and therefore all Cl3 = as= ..... e. A= (2r+1) r =0,1,2 ..... E 1 or 1 /2nw = (2r+ 1) = 2 (r+'2) or E = (r+1/2) nco, r =0,1,2 ........ 89) thus the energy eigen values are %nco, ~ nco, %nCO, .... obviously, quantized and have a definite minimum value viz. These are, %nco. This is called zero point energy and is characteristic of quantum mechanism.
