OBJECTIVES:

  • To introduce the basic concepts of DC and AC circuits behavior
  • To study the transient and steady state response of the circuits subjected to step and sinusoidal
  • To introduce different methods of circuit analysis using Network theorems, duality and topology.

UNIT I    BASIC CIRCUITS ANALYSIS AND NETWORK TOPOLOGY                              

Ohm‘s Law – Kirchhoff‘s laws  –  Mesh current and node voltage method of  analysis  for D.C  and -circuits – Network terminology – Graph of a network – Incidence and reduced incidence matrices – Trees –Cutsets – Fundamental cutsets – Cutset matrix – Tie sets – Link currents and Tie set schedules -Twig voltages and Cutset schedules, Duality and dual

UNIT II   NETWORK THEOREMS FOR DC AND AC CIRCUITS                                         

Network theorems  -Superposition  theorem,  Thevenin‘s  theorem,  Norton‘s  theorem,  Reciprocity theorem, Millman‘s theorem, and Maximum power transfer theorem ,application of Network theorems- Network reduction: voltage and current division, source transformation – star delta conversion.

UNIT III   RESONANCE AND COUPLED CIRCUITS                                                                

Resonance – Series resonance – Parallel resonance – Variation of impedance with frequency – Variation in current through and voltage across L and C with frequency – Bandwidth – Q factor – Selectivity. Self inductance –  Mutual  inductance  –  Dot  rule  – Coefficient  of  coupling  –  Analysis of multiwinding coupled circuits – Series, Parallel connection of coupled inductors – Single tuned  and double tuned coupled circuits.

UNITIV  TRANSIENT ANALYSIS                                                                                          

Natural response-Forced response – Transient response of RC, RL and RLC circuits to excitation by Step Signal, Impulse Signal and exponential sources – Complete response of RC, RL and RLC Circuits to sinusoidal excitation.

UNIT V  TWO PORT NETWORKS                                                                                         

Two port networks, Z parameters, Y parameters, Transmission (ABCD) parameters, Hybrid(H) Parameters, Interconnection of two port networks, Symmetrical properties of T and π networks.
