This course is designed to build a comprehension of direct current and alternating current circuits, including calculations and diagnostics. Ohm's law will be applied to analyze both simple and complex electrical circuits, demonstrating the relationships among volts, ohms, amps, and watts in series, parallel, and combination circuits.
The course covers inductance, capacitance, reactance, and impedance, emphasizing how these properties depend on frequency.
Students will study the construction and electromagnetic principles of DC and AC motors. The course examines how rotating magnetic fields drive motors and explores applications of DC and AC generators, from residential backup units to large-scale power generation and its interaction to the power grid.
