This UQuest question bank has been prepared strictly as per the AKTU (Dr. APJ Abdul Kalam Technical University, Lucknow) First Year B.Tech syllabus for the course AEE101B / AEE201B — Fundamentals of Electrical Engineering, an Engineering Science Course (ESC) applicable to the CE, ME, TX and CH streams across Semester I and II. This is a Basic Electrical Engineering course framed around industrial and instrumentation applications relevant to Civil, Mechanical, Textile and Chemical engineering students — no electronics device theory is included. It builds the ability to analyse DC and single-phase AC circuits, understand three-phase power systems used in industrial motors and drives, work with transformers and electrical machines, and apply electrical safety knowledge to everyday industrial and laboratory situations such as workshop motors, water pumps, lathe machines, and electricity billing. Every unit below is covered with three categories of practice questions, each with complete, concise, exam-ready solutions — including worked numerical problems on DC network analysis, AC power calculations, three-phase power measurement, and transformer ratios/efficiency where the syllabus calls for analysis — to help students revise concepts and prepare thoroughly for the semester end examination. Question pattern followed per unit: • Section A: 15 Multiple Choice / True-False Questions — with correct answer and explanation. • Section B: 12 Short Answer Type Questions — with concise, exam-ready answers. • Section C: 12 Long Answer Type Questions — with structured explanations, illustrative examples, and diagrams. ★★ Most Important and ★ Important tags mark questions with the highest probability of appearing in the AKTU semester examination, based on topic weightage and repetition trends — prioritize these while revising. This subject builds a working, industry-applications-first understanding of basic electrical engineering across five units of uneven weightage: basic electrical quantities and DC circuits (20% — charge, current, voltage, resistance, power and energy, Ohm's law, series/parallel resistors, KVL, KCL, simple mesh and nodal analysis, and Thevenin's theorem), single-phase AC circuits and power (20% — peak/RMS/average values, phasor representation, R/L/C series and parallel circuits, impedance and admittance, active/reactive/apparent power, power factor and its correction using shunt capacitors, and single-phase wattmeter measurement), three-phase systems (10% — balanced star and delta connections, phase and line voltages/currents, three-phase power, and the two-wattmeter method), transformers and electrical machines (30%, the largest unit — single-phase transformer working principle, EMF equation, voltage/current ratio, losses and efficiency, step-up/step-down transformers, the no-load equivalent circuit and phasor diagram, DC motor types/working principle/back EMF/torque, and three-phase induction motor rotating field, slip, torque-speed curve, and DOL/star-delta starting), and electrical safety and emerging applications (20% — electrical hazards, earthing and grounding, working principle of fuses and circuit breakers, laboratory electrical safety, and applications such as fluorescent lamps, motors used in water pumps and lathe machines, and the key components of an electricity bill). Sixteen labelled diagrams illustrate key circuits and concepts across all five units — from Ohm's-law dividers and KVL/KCL mesh-nodal analysis to transformer phasor diagrams, DC/induction motor operation, and fuse/MCB trip mechanisms. Two full-length Model Question Papers are included at the end of this book, formatted exactly in the official AKTU BTECH theory-examination pattern (Section A / B / C, CO and Level columns, 3 Hours, 70 Marks), so students can attempt a complete, timed mock test as final practice.
