About this previous year paper
This document contains the complete B.Tech (Semester II) Theory Examination Question Paper for Fundamentals of Electrical Engineering, Subject Code BEE201, for the academic session 2023–24. The question paper is designed to evaluate a student’s conceptual understanding and analytical ability across major areas of electrical engineering such as network analysis, AC/DC circuits, transformers, induction motors, synchronous machines, magnetic materials, earthing systems, and three-phase power calculations.
The paper is divided into three structured sections, each assessing a different level of electrical engineering skills—from basic definitions to detailed problem solving and long analytical explanations.
SECTION A — Short Conceptual Questions (2 marks each)
This section contains seven short-answer questions testing the fundamentals of electrical engineering. Topics include:
Unilateral & bilateral elements
Kirchhoff’s laws
Average power in capacitive circuits
Conditions for positive voltage regulation
Transformer efficiency and max-efficiency condition
Slip and rotor frequency in induction motors
Common electrical installation problems
These questions check quick recall and clarity of basic electrical principles.
SECTION B — Analytical & Numerical Questions (7 marks each)
Students must attempt any three questions. This section evaluates deeper analytical understanding, including:
Nodal analysis for branch current calculation
Derivation of dynamic impedance (ZD) of an RLC parallel circuit under resonance
Purpose and formation of the equivalent circuit of a transformer
Types of magnetic materials and their explanations
Earthing, neutral grounding, and importance of electrical safety
This section blends circuit theory, derivations, safety concepts, and electrical machine fundamentals.
SECTION C — Long Descriptive & Problem-Solving Questions (7 marks each)
Each sub-section contains numerical or theory-intensive questions such as:
Mesh analysis to find branch currents
Three-phase load calculations: line voltage, current, power factor, and total power
Transformer design & EMF equation derivation
Efficiency, equivalent impedance, copper loss, and supply current calculations
Resonance in series RLC circuits and expressions for:
– Cut-off frequencies
– Bandwidth
– Quality factor
Working principle of 3-phase synchronous motors
Torque–slip characteristics of induction motors
Cable construction, insulating layer, and metallic sheath functions
Lightning protection concepts
These questions test students’ understanding of real-world electrical systems and machine operations.
Sample Questions (1–2 from the paper)
“What is Kirchhoff’s law?” — A foundational question testing basic circuit theory.
“Explain the phenomenon of resonance in a series R-L-C circuit and derive expressions for cut-off frequencies, bandwidth, and quality factor.”
— A long analytical question assessing AC circuit understanding.
These examples represent the nature of conceptual and analytical questions throughout the paper.
