The Fundamentals of Electrical Engineering (BEE201) Question Paper for the B.Tech Semester II (2022–23) examination is designed to evaluate a student's core understanding of electrical circuits, AC/DC analysis, electrical machines, and essential power system concepts. Carrying 70 marks, this exam is divided into structured sections that test conceptual clarity, analytical thinking, and practical problem-solving skills.
The paper begins with Section A, consisting of short-answer questions on key electrical engineering fundamentals. Students answer questions relating to KCL and KVL laws, active and passive circuit elements, average power in purely inductive circuits, phasor diagrams of a two-winding transformer under no-load condition, types of DC machines, classification of electrical cables, and the average value of sinusoidal currents. These questions assess quick recall and clarity of basic concepts.
Section B features more elaborate descriptive and numerical questions that require understanding and methodical writing. Students may be asked to apply nodal analysis to determine currents in resistor networks, derive expressions for instantaneous and average power in RLC series circuits, explain transformer losses and ways to minimize them, derive the torque equation for DC machines, and describe types of batteries with diagrams. This section focuses on analytical capability and logical explanation.
In Section C, the paper includes long-answer, multi-step questions that test technical depth. Topics include forming mesh equations for complex networks, deriving the phase and line quantity relationship in a 3-phase star connection using phasor diagrams, deriving the resonant frequency equation for RLC circuits, and constructing instantaneous power waveforms. This section measures a student’s higher-order problem-solving skills.
The last section also covers application-oriented concepts such as calculating transformer efficiency, drawing the equivalent circuit of a transformer, describing the working and torque–slip characteristics of a three-phase induction motor, explaining different DC machines with circuit diagrams, drawing the constructional diagram of a 3-core armoured XLPE cable, and explaining the working principle of an MCB with diagrams.
Overall, the BEE201 question paper provides a balanced and comprehensive assessment of a student’s foundation in electrical engineering. It strengthens analytical thinking, circuit-solving skills, and understanding of electrical machines—essential for progressing into advanced engineering subjects.
