BEE303 CIRCUIT THEORY


OBJECTIVE : To teach all the circuit theorems and solution of d.c. , single phase and three phase a.c. circuits.


1. BASIC CIRCUIT CONCEPTS:

Review of Basic concepts - D.C. and A.C. circuits - R , L and C elements - phasor diagram - complex impedance- real and reactive power - series and parallel circuits - loop and nodal analysis.

2. NETWORK THEOREMS AND TRANSFORMATIONS:

Voltage - current source transformation - star-delta transformation - superposition - reciprocity - substitution - Thevenins - Norton's - Maximum power transfer theorems.

3. RESONANCE AND COUPLED CIRCUITS:

Series and parallel resonance - bandwidth - Q factor - inductively coupled circuits - coefficient of coupling - dot convention - multi - winding coupled circuit - analysis of coupled circuit.

4. THREE - PHASE CIRCUITS:

Solution of balanced 3Ø circuits - power and power factor calculations by two wattmeter method - solution of unbalanced circuits.

5. TIME RESPONSE OF CIRCUITS:

Time response of RL, RC and RLC circuits for zero input and step and sinusoidal inputs using laplace transform method.
