## CIRCUIT THEORY |

UNIT I BASIC CIRCUITS ANALYSIS |

Ohm’s Law – Kirchoffs laws – DC and AC Circuits – Resistors in series and parallel
circuits – Mesh current and node voltage method of analysis for D.C and A.C.
circuits. |

UNIT II NETWORK REDUCTION AND NETWORK THEOREMS FOR DC
AND AC CIRCUITS: |

Network reduction: voltage and current division, source transformation – star delta
conversion.
Thevenins and Novton & Theorem – Superposition Theorem – Maximum power
transfer theorem – Reciprocity Theorem. |

UNIT IIIRESONANCE AND COUPLED CIRCUITS |

Series and paralled resonance – their frequency response – Quality factor and
Bandwidth - Self and mutual inductance – Coefficient of coupling – Tuned circuits –
Single tuned circuits. |

UNIT IVTRANSIENT RESPONSE FOR DC CIRCUITS |

Transient response of RL, RC and RLC Circuits using Laplace transform for DC input
and A.C. with sinusoidal input. |

UNIT VANALYSING THREE PHASE CIRCUITS |

Three phase balanced / unbalanced voltage sources – analysis of three phase 3-wire
and
4-wire circuits with star and delta connected loads, balanced & un balanced – phasor
diagram of voltages and currents – power and power factor measurements in three
phase circuits. |
