12026105 ELECTRICAL ENGINEERING 1                                        3(3-0-6)


This course includes the following topics: modern physics, DC and AC circuit analysis , Ohm’s law, Kirchhoff’s law, nodal and mesh analysis, Thevenin’s and Norton’s theories, superposition, The elements are analyzed in the circuits as the first and second order circuits. All the responses in the transient and steady states are also described. The phasor is also introduced in the subject, which simplifies the analysis of the first and second order circuits, especially in the AC steady state. Average power and power factor calculation, relations of average power and power factors, power factor correction, linear and ideal transformers and three phases circuits are studied.
