The course includes the analysis of circuits with resistors, inductors, capacitors, and independent and dependent voltage and current sources. Many analysis techniques will be applied to DC and AC circuits. Differential equations will be used to find the transient response of circuits. Power calculations will be performed on both DC and AC circuits, including an introduction to three- phase AC power. This course is required for most engineering Bachelors of Science degrees.Usually HeldMon, Wed 12:15pm–1:05pm, Wed 11:45am–12:35pm, Wed 12:15pm–1:20pm
