## Electrical Circuit Analysis – I

### Preamble:

This course introduces the fundamental ideas of circuit analysis that is that the foundation for all subjects of the technology discipline. the stress of this course is arranged on the fundamental analysis of circuits which has single section circuits, magnetic circuits, network theorems, transient analysis and constellation.
Learning Objectives:

• to check the ideas of passive components, varieties of sources and numerous network reduction techniques.

• to know the applications of constellation to electrical circuits.

• to check the idea of magnetic coupled circuit.

• to know the behaviour of RLC networks for curving excitations.

• to check the performance of R-L, R-C and R-L-C circuits with variation of 1 of the parameters and to know the idea of resonance.

• to know the applications of network theorems for analysis of electrical networks.

#### UNIT-I

Introduction to Electrical Circuits Passive elements and their V-I relations. Sources (dependent and independent) -Kirchoff’s laws, Network reduction techniques(series, parallel, series – parallel, star-to-delta and deltato-star transformation). supply transformation technique, nodal analysis and mesh analysis.

#### UNIT-II

constellation Definitions of Graph and Tree, Basiccutset and tieset matrices for planate networks, Loop and nodal ways of research of networks with dependent and freelance voltage and current sources, twinity and Dual networks.

#### UNIT-III

Magnetic Circuit Basic definition of MMF, flux and reluctance. Analogy between electrical and magnetic circuits.Faraday’s laws of magnetism induction idea of self and coefficient.
