ELEC105 - Circuit Theory I

The concepts of current, voltage, power, energy, and resistance are studied. Topics include DC and AC sources, capacitance, inductance, and magnetism. Resistive circuits are analyzed using Ohm's and Kirchhoff's Laws and computer-aided circuit analysis using SPICE is included. Corequisite: MATH205 College Mathematics I or MATH230 College Mathematics B. Day and The Arioch Center Course.
