ELECTRICAL CIRCUITS
OBJECTIVES:
This course introduces the basic concepts of network and circuit analysis which is the
foundation of the Electrical Engineering discipline. The emphasis of this course if laid on
the basic analysis of circuits which
includes network analysis, 1-phase ac circuits,
magnetic circuits.
Unit –I:
Introduction to Electrical Circuits: Concept of Network and Circuit, Types of elements,
Types of sources, Source transformation. R-L-C Parameters, Voltage–Current relationship
for Passive Elements (for different input signals –Square, Ramp,
Saw tooth and
Triangular), Kirchhoff’s Laws.
Unit –II:
Network Analysis: Network Reduction Techniques-Resistive networks, Inductive networks
and capacitive networks- Series, Parallel, Series-Parallel combinations, Star–to-Delta and
Delta-to-Star Transformation. Mesh Analysis and Super mesh,
Nodal Analysis and Super
node for DC Excitation. Network topology-Definitions, Graph, Tree, Basic Cut set and Basic
Tie set Matrices for Planar Networks.
