Textbook in PDF format

This book, Calculations on Electricity and Heat Energy, has been carefully written to teach you the major topics in circuit calculations and heat energy calculations. This eBook is a 'physics teacher' which is suitable for students in high schools and in colleges. It will also serve as a useful tool for students who are preparing for entrance examinations into colleges and universities. Numerous worked examples have been included in each topic to fully cover every complexity the topic might contain. Numerous exercises at the end of each chapter are intended to test students' understanding of the topic.
