Module 1:

DC circuits: Ohm’s law and Kirchhoff’s laws, analysis of series, parallel and series-parallel circuits excited by independent voltage sources. Power and energy, maximum power transfer theorem appliedto the series circuit and its applications. Single-phase circuits: Generation of sinusoidal voltage, frequency of generated voltage, average value, RMS value, form, and peak factors. Voltage and current relationship, with phasor diagrams, in R, L, and C circuits. Teaching Learning Process Chalk and talk method.

Module 2:

Single-phase circuits (continued): Analysis of R-L, R-C, R-L-C Series and Parallel circuits, Real power, reactive power, apparent power, and Power factor. Measurement of power. Three-phase circuits: Generation of three-phase power, representation of balanced star (3 wire and 4 wire system) and delta connected loads, the relation between phase and line values of voltage and current from phasor diagrams, advantages of three-phase systems. Measurement of three-phase powerby two-wattmeter method.
