Fundamentals of DC and AC CircuitsFundamentals of DC Circuits : Ohm's law, Kirchhoff's law, Simple resistive circuits - Effect of series and parallel resistances - Mesh and Nodal analysis - Simple problems.Fundamentals of AC Circuits : RMS and average values of sine wave, Form factor, Peak factor. Single phase AC circuits - Impedance, Power and power factor - RL, RC, RLC circuits - Simple AC circuits - Problems.Fundamentals of Magnetic CircuitsOhm's law of magnetic circuit, Simple and composite magnetic circuits, Effect of air gap - Leakage factor - fringing effect - Simple problems. Faraday's law of electromagnetic induction - Self and Mutually induced EMF - Statically and Dynamically induced EMF - Simple problems.DC Machines and TransformersDC Machine : Construction - EMF equation of DC generator - Types of generators and motors - Characteristics.Transformer : Construction - EMF equation - Transformation ratio - Types of transformers - Instrumentation transformer.Induction MachinesThree Phase Induction Motor : Construction, Types - Principle of operation - Torque equation - Slip Vs Torque characteristics of cage and wound rotor.Single Phase Induction Motor : Principle of operation-Types - Applications.Power SuppliesHalf wave and full wave rectifiers - Bridge rectifier - Types of filters - Voltage regular - Introduction to SMPS and UPS.The capacitor remains in the circuit only at start hence it is called capacitor start motors. In case of capacitor start capacitor run motor, there is no centrifugal switch and capacitor remain permanently in the circuit. This improves the power factor.
