Basic Electrical & Electronics Engineering

Basic Electrical & Electronics Engineering is an English medium textbook for engineering students of the II Semester (old scheme) course. The book opens with basic concepts: electric current, Ohm's law, circuit components, power and energy, electromagnetic induction with Faraday's and Lenz's laws, and network sources. Circuit analysis follows with series-parallel circuits, Kirchhoff's laws, node-voltage and mesh-current methods, and the superposition, Thevenin, Norton and maximum power transfer theorems. Further chapters explain transformers (construction, phasor diagrams, equivalent circuit, voltage regulation, OC and SC tests, losses and efficiency, auto-transformer), AC circuits (RMS and average values, form and peak factor, phasors, single phase RLC circuits, three phase systems), and DC and AC machines including induction and synchronous machines. Basic electronics covers semiconductors, PN junction and Zener diodes, rectifiers, BJT and FET, the binary system, Boolean algebra and logic gates. The last chapter deals with electrical measuring instruments such as moving coil and moving iron instruments, multimeter, wattmeter and energy meters. Written by Dr. R. A. Gupta, Dr. Ajay Kumar Bansal and Dr. Virendra Sangtani, this 528-page book suits engineering students studying the subject in the second semester.
