Basic Electrical Engineering — Unit-wise Notes
Four units in one file. Circuit concepts: active and passive elements, source transformation, Kirchhoff's laws, mesh and nodal analysis, star-delta, and the superposition, Thevenin and Norton theorems with numericals. Single-phase AC: waveforms, average and RMS values, form and peak factors, phasors, series and parallel RLC, resonance, bandwidth and Q, power factor and its improvement. Magnetic circuits: B-H curve, hysteresis and eddy current losses, series and parallel calculations, and the single-phase transformer — construction, EMF equation, equivalent circuit, losses and efficiency. Machines: DC generator EMF and motor torque equations with applications, and the three-phase induction motor with slip-torque characteristics.
