ELT 121 - AC/DC Circuit Analysis

4 Credits

A one-semester algebra-based electric circuit analysis course for majors mainly in Electrical Engineering Technology, Mechanical Technology and Optical Technology, as well as others requiring an introduction to both DC and AC signal driven circuit analysis of series, parallel and series parallel resistive circuits and series RC circuits. Topics include: voltage, current, resistance, conductance, Ohm's law, Kirchoff's Voltage and Current laws, voltage and current dividers equations, power, capacitance, a brief introduction to inductance, RC time constant circuits, capacitive reactance and impedance, superposition, Thevenin, Norton, Theorems, computer analysis, and an introduction to troubleshooting. Lab teaches use of digital multimeters, analog VOM, power supplies, dual-trace oscilloscope, function generators, and an introduction to computer generated circuit analysis using Multisim, the concept of circuit loading and meter frequency limitations.

Prerequisite(s): MCC Level 8 or higher Mathematics Placement OR concurrent registration with MTH 152
