AKTU Fundamentals of Electronics Engineering (AEC101A/AEC201A) Question Bank with Solutions – B.Tech 1st Year

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 AEC101A / AEC201A — Fundamentals of Electronics Engineering, an Engineering Science Course (ESC) applicable to the CSE, EE and ECE streams across Semester I and II. Every unit below is covered with three categories of practice questions, each with complete, concise, exam-ready solutions — including worked numerical and circuit-design problems where the syllabus calls for analysis and design — 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 foundation in analog and digital electronics across five units: diodes and power supply circuits (p-n junction behaviour, half-wave and full-wave rectifiers, Zener voltage regulators, LEDs), transistors as switches and amplifiers (BJT regions of operation, BJT/MOSFET switching circuits, the common-emitter amplifier), operational amplifiers (ideal characteristics, inverting/non-inverting amplifiers, comparators and signal-conditioning applications), digital electronics basics (number systems, logic gates, Boolean algebra, K-maps, adders, multiplexers and flip-flops), and electronic systems and emerging applications (microcontrollers, ADC/PWM, UART/SPI/I2C, sensor signal chains, wireless basics and power management, tied to real IoT/EV products). Fifteen labelled circuit diagrams (three per unit) illustrate key circuits and concepts such as the diode V-I characteristic, bridge rectifier and Zener regulator, BJT/MOSFET switching circuits, op-amp configurations, logic gates and K-map reduction, and the microcontroller/sensor signal chain. 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.
