DIPLOMA IN ELECTRICAL ENGINEERING

SEMESTER: THIRD

COURSE CODE: 302 NAME OF COURSE: ELECTRICAL CIRCUITS

COURSE CONTENTS

1. CIRCUIT ANALYSIS

Active and passive elements, ideal current source and voltage source.

Unilateral and bilateral elements.

Number of loops, nodes, branches of a network. Analysis of networks by

"Mesh" and "Node" methods. T and ∏ terminal networks, input and output

impedance and admittance.

2. NETWORK THEOREMS

Maxwell’s loop theorem, Nodal analysis, Superposition, Thevenin's, Nortons'

and maximum power theorems with numerical problems.

3 SINGLE PHASE A.C. CIRCUITS

Representation of A.C. quantity by phasor methods, rectangular and polar

co-ordinates. RLC series and parallel combinations.

Impedance, power in single phase circuits. Concept of power factor,

conductance, admittance and susceptance. Series and parallel circuits,

resonance in series circuit.

4. POLYPHASE CIRCUITS

Concept of poly phase A.C. circuits, advantages over single phase.

Generation of three phase voltage system. Three phase circuits, phase

sequence, vector and wave diagrams. Star and delta connections, phase and

line values of current and voltage, power in three phase circuits. Balanced

and unbalanced systems

5. TRANSIENTS

Concept of transient, variation of current when connected to D.C. or A.C.

series circuit (R.L. combination and R.C. combination). Time constant.
