JNTUK R23 B.Tech EEE II Year I Semester (2-1) Syllabus & Subject-wise Topics

Complex Variables & Numerical Methods

builds the mathematical toolkit electrical engineers lean on when a problem has no neat closed-form answer: numerical methods for root-finding, interpolation and integration, plus the theory of complex functions.

• Unit 1: Iterative root-finding methods (bisection, secant, false position, Newton-Raphson) and interpolation (Newton’s forward/backward, Lagrange’s formula)
• Unit 2: Numerical integration (trapezoidal, Simpson’s 1/3 and 3/8 rules) and solving ODEs (Taylor series, Picard’s method, Euler’s method, Runge-Kutta, Milne’s predictor-corrector)
• Unit 3: Functions of a complex variable — continuity, differentiability, Cauchy-Riemann equations, and complex integration via Cauchy’s integral theorems
• Unit 4: Series expansions (Taylor, Maclaurin, Laurent), types of singularities, and the residue theorem for evaluating real integrals
• Unit 5: Conformal mapping — standard transformations, translation, rotation, bilinear transformations, fixed points and cross-ratio

Universal Human Values – Understanding Harmony and Ethical Human Conduct

a foundation course that asks engineering students to examine their own values and relationships before examining circuits, building self-awareness and an ethical compass for professional life.

• Unit 1: Introduction to value education — self-exploration and the basis of happiness and prosperity
• Unit 2: Harmony within the individual — the relationship between the self and the body
• Unit 3: Harmony in the family and society — trust, respect and the foundations of human relationships
• Unit 4: Harmony with nature — interconnectedness across the orders of existence
• Unit 5: Implications for professional ethics — translating holistic understanding into ethical human conduct

Electromagnetic Field Theory

develops the vector-calculus foundation for how electric and magnetic fields behave in space, underlying everything from cable design to the machine flux analysis that shows up later in the EEE curriculum.

• Unit 1: Vector analysis (coordinate systems, gradient, divergence, curl) and electrostatics — Coulomb’s law, Gauss’s law, electric potential
• Unit 2: Conductors, dielectrics and capacitance — dipoles, polarization, boundary conditions, and energy stored in electric fields
• Unit 3: Magnetostatics — Biot-Savart’s law, Ampere’s circuital law, magnetic force and torque
• Unit 4: Self and mutual inductance of solenoids, toroids and coaxial cables, and magnetic energy storage
• Unit 5: Time-varying fields — Faraday’s law, displacement current, and Maxwell’s equations in integral and point form

Electrical Circuit Analysis-II

extends first-year circuit theory into three-phase systems, transient behaviour and frequency-domain tools that electrical engineers use daily to analyse real networks.

• Unit 1: Analysis of three-phase balanced and unbalanced circuits, and power measurement techniques
• Unit 2: Laplace transforms and transient response of R-L, R-C and R-L-C circuits
• Unit 3: Two-port network parameters (impedance, admittance, hybrid, ABCD) and their interconnection
• Unit 4: Fourier series analysis of circuits under periodic, non-sinusoidal excitation
• Unit 5: Filter design — low-pass, high-pass, band-pass and band-elimination constant-k filters

DC Machines & Transformers

covers the construction, operation and testing of DC generators, DC motors and transformers, the electromechanical building blocks that reappear throughout the power-focused subjects ahead.

• Unit 1: DC generator construction, EMF equation, excitation methods and characteristics
• Unit 2: DC motor starting, speed control methods, and standard testing procedures (Swinburne’s, Hopkinson’s, brake test)
• Unit 3: Single-phase transformer construction, operation, phasor diagrams and equivalent circuit
• Unit 4: Transformer testing — OC/SC tests, Sumpner’s test, parallel operation and auto-transformers
• Unit 5: Three-phase transformer connections, vector groups, and on-load/off-load tap changers

Electrical Circuit Analysis-II and Simulation Lab

pairs hands-on measurement with simulation software so students verify circuit theorems and network parameters using both real instruments and software tools.

• Measuring active/reactive power for balanced and unbalanced three-phase loads, and determining Z, Y, ABCD and hybrid network parameters
• Simulation-based verification of KCL/KVL, mesh/nodal analysis, superposition, maximum power transfer, reciprocity, Thevenin’s and Norton’s theorems
• Analysing transient response of RL/RC/RLC circuits and resonance, plus verifying self and mutual inductance

DC Machines & Transformers Lab

hands-on testing of DC machines and transformers that connects classroom theory on speed control, efficiency and regulation to measurable machine behaviour on the test bench.

• Speed control and braking tests on DC shunt motors, plus Swinburne’s, Hopkinson’s and field tests on DC machines
• Load tests on DC shunt and compound generators and DC series machines
• OC/SC and Sumpner’s tests, Scott connection, parallel operation, and core-loss separation for single-phase transformers

Data Structures Lab

introduces core data structures and algorithmic thinking through hands-on programming, giving EEE students the programming foundation the later software-heavy labs assume.

• Unit 1: Arrays, searching (linear, binary) and sorting (bubble, selection, quick sort)
• Unit 2: Singly, doubly and circular linked lists and their applications
• Unit 3: Stack implementation using arrays and linked lists, with expression evaluation and backtracking applications
• Unit 4: Queue, circular queue and deque implementation and applications
• Unit 5: Binary trees and binary search trees — traversal, insertion and deletion

Environmental Science

a mandatory awareness course on natural resources, ecosystems and pollution control, aimed at making engineering graduates conscious of the environmental footprint of the technology they build.

• Unit 1: Multidisciplinary nature of environmental studies and natural resources (forest, water, mineral, food, energy)
• Unit 2: Ecosystem structure and function, and biodiversity conservation
• Unit 3: Types and control of environmental pollution, and solid waste/disaster management
• Unit 4: Sustainable development, environmental legislation and social issues
• Unit 5: Population growth, human health and the environment
