This course covers the fundamental principles of circuit theory commonly used in engineering research and science applications. Techniques and principles of electrical circuit analysis include basic concepts such as voltage, current, resistance, conductance, impedance, power, energy, etc., along with Ohm’s, and Kirchhoff’s laws. Furthermore, the taught circuit analysis techniques include Nodal and Mesh Analysis, superposition, and source transformation, Thevenin and Norton’s Theorems, and maximum power transfer. Also, basic electric circuit analysis techniques for series, parallel, series-parallel for resistive circuits, transient and steady-state responses of RLC circuits; circuits with DC and sinusoidal sources, steady-state power, and operational amplifiers, balanced and unbalanced three phase circuits, single phase and three phase transformers. The AC part of the course includes sinusoids and phasor analysis, elements of AC circuits, impedance and admittance, analysis of AC circuits, and power calculation in AC circuits. Prerequisite: PHYS 233, PHYSL 233
