(SEM I) THEORY EXAMINATION 2020-21 BASIC OF ELECTRICAL ENGINEERING

This document contains the official AKTU B.Tech 1st Semester Question Paper for Basic of Electrical Engineering (KEE101T). It is the exact 100-mark university exam paper, designed for the Theory Examination 2020–21, and follows the complete AKTU format with Sections A, B, and C. This question paper is ideal for students preparing for end-semester exams, internal assessments, and revising key electrical engineering fundamentals.

Basic of Electrical Engineering is a core subject for all first-year engineering students across branches such as CSE, IT, ECE, ME, CE, EE, EN, and others. This paper helps students understand electrical principles, circuits, machines, AC/DC fundamentals, and numerical problem-solving.

What This Question Paper Covers (Detailed Overview)

SECTION A – 20 Marks (10×2)

This section contains 10 short, concept-based questions, checking basic understanding. Topics include:

Ohm’s Law

Kirchhoff’s laws

RMS/average value

Power factor

Series & parallel circuits

Inductor & capacitor definitions

DC machine basics

Transformer fundamentals

AC waveform terminology

Electrical power & energy concepts

These questions help students revise essential definitions and formulas.

SECTION B – 30 Marks (3×10)

Students must attempt any 3 out of 5 descriptive questions. Topics generally include:

Derivations & explanations of electrical laws

Series/parallel resistance problems
