Introduces the basic concepts of electricity as it applies to AC circuits. Explains inductance, capacitance, and the phasor relationships between electrical signals Explains the schematic symbols for devices used in AC circuits. Determines the total impedance for series and parallel combinations of resistors, inductors, and capacitors. Uses Ohm’s law, Kirchhoff’s voltage law, and Kirchhoff’s current law to solve combination AC circuits using phasor analysis. Also covers include series and parallel resonant frequencies, harmonics, filters, and time constants. Uses oscilloscopes and meters during lab activities to apply concepts learned during class. Credit may be earned in SKET 120 or ET 120 but not both.
