Ishan’s Principles of Electrical Engineering is a comprehensive and student-friendly textbook designed to develop a strong understanding of basic electrical engineering concepts. The book is highly useful for polytechnic, diploma, and engineering students who need simple explanations, clear theory, important laws, circuit concepts, and practical knowledge for examinations.
The book covers all essential topics such as Electrical Fundamentals, D.C. Circuits, Electrostatics and Magnetostatics, Electromagnetic Induction, Batteries, and Practicals. It begins with the nature of electricity, charge, resistance, laws of resistance, capacitors, heating effect of electric current, and energy stored in capacitors. It further explains important D.C. circuit topics including Ohm’s Law, series and parallel circuits, voltage and current sources, Wheatstone Bridge, Kirchhoff’s Laws, and Star-Delta Transformation.
The book also provides clear coverage of magnetic field, magnetic flux, electromagnetism, magnetic circuits, Faraday’s Laws, Lenz’s Law, Fleming’s rules, self and mutual induction, hysteresis, eddy currents, and energy stored in an inductor. The battery section explains electrolysis, cells, lead-acid batteries, lithium-ion batteries, charging methods, battery characteristics, maintenance, and safe disposal in a practical manner.
