Principles Of Electrical Engineering

Principles of Electrical Engineering - Standards and Units: the basic electric circuit and Ohm's Law, resistors in series and parallel, double subscript notation, cells with internal resistance. Circuit Analysis: Kirchoff's Laws and Thevenin's Theorem. Electromagnetism: magnetic field strength, magnetic flux density, permeability, Faraday's Law and Lenz's Law, inductance and magnetic circuits Electrostatics: electric field strength, electric flux density, permittivity, capacitance, capacitors in series and parallel, energy stored in a capacitor Alternating Current: frequency, period, amplitude, angular frequency, average value, r.m.s. value and form factor, representation of alternating waveforms by phasor diagrams, addition and subtraction of phasors. Single Phase circuits: circuits with resistance, inductance and capacitance, phase relationships in single phase circuits, power measurement using a wattmeter, power factor angle and power diagrams. Three Phase circuits: star and mesh connected systems with balanced loads, relationships between line and phase voltages/currents in star and mesh connected systems, power measurement using two wattmeters, power factor angle, power diagrams, three-phase squirrel cage induction motors Principles of Electrical Engineering - The basic electric circuit and Ohm’s Law.
