Current Electricity and DC Circuits: Concepts and Problems in Physics

This text book is primarily intended for students who are preparing for the entrance tests of JEE (MAIN and Advanced)/NEET/Olympiad and other esteemed colleges in same fields. This text is equally useful to the students preparing for their school exams.Key Features: 1. In this textual material even a trivial concept is substantialized in this way to make it lucid and easy to grasp. Every concept is given in student friendly language followed by a ladder of illustration and checkpoint questions. The solution of checkpoint is provided with problem solving approach and discussion. 2. Special attention is given to all tricky topics (like- uniform and non uniform electric currents radial flow of current calculation of resistance and resistivity  application of Kirchhoffs rules in complex circuit problems identifying symmetries in circuits ladder problems star-delta transformation ammeter voltmeter and potentiometer etc.) so that student can easily solve them with fun. 3. At the end of the theory part there are miscellaneous solved examples which involve the application of multiple concepts of this chapter. 4. To test the understanding level of students multiple choice questions conceptual questions practice problems with previous years JEE Main and Advanced problems are provided at the end of the whole discussion. Answer keys with hints and solutions are provided at the end of the chapter.
