ELECTRICAL CIRCUIT ANALYSIS
Objective :
This course introduces the basic concepts of circuit analysis which is the foundation for all subjects of the
Electrical Engineering discipline. The emphasis of this course is laid on the basic analysis of circuits which
includes Single phase circuits, magnetic circuits, theorems, transient analysis and network topology.
UNIT – I Introduction to Electrical Circuits
Circuit Concept – R-L-C parameters – Voltage and Current sources – Independent and dependent
sources-Source transformation – Voltage – Current relationship for passive elements – Kirchhoff’s laws –
network reduction techniques – series, parallel, series parallel, star-to-delta or delta-to-star transformation.
UNIT – IIMagnetic Circuits
Magnetic Circuits – Faraday’s laws of electromagnetic induction – concept of self and mutual inductance –
dot convention – coefficient of coupling – composite magnetic circuit – Analysis of series and parallel
magnetic circuits
UNIT – III Single Phase A.C Circuits
R.M.S and Average values and form factor for different periodic wave forms, Steady state analysis of R, L
and C (in series, parallel and series parallel combinations) with sinusoidal excitation – Concept of
Reactance, Impedance, Susceptance and Admittance – Phase and Phase difference – concept of power
factor, Real and Reactive powers – J-notation, Complex and Polar forms of representation, Complex
power – Locus diagrams – series R-L, R-C, R-L-C and parallel combination with variation of various
parameters – Resonance – series, parallel circuits, concept of band width and Q factor.
UNIT – IV Three Phase Circuits
Three phase circuits: Phase sequence – Star and delta connection – Relation between line and phase
voltages and currents in balanced systems – Analysis of balanced and Unbalanced 3 phase circuits –
Measurement of active and reactive power.
UNIT – V Network topology
Definitions – Graph – Tree, Basic cutset and Basic Tieset matrices for planar networks – Loop and Nodal
methods of analysis of Networks with independent voltage and current sources – Duality & Dual networks.
UNIT – VI Network theorems (without proofs)
Tellegen’s, Superposition, Reciprocity, Thevenin’s, Norton’s, Maximum Power Transfer, Millman’s and
Compensation theorems for d.c. and a.c. excitations.
UNIT – VII Transient Analysis
Transient response of R-L, R-C, R-L-C circuits (Series combinations only) for d.c. and sinusoidal
excitations – Initial conditions – Solution using differential equation approach and Laplace transform
methods of solutions.
UNIT – VIII Network Parameters
Two port network parameters – Z, Y, ABCD and hybrid parameters and their relations– – concept of
transformed network – 2-port network parameters using transformed variables.
