Electrical 1 is designed to build and strengthen a technician’s foundational electrical skills and proficiency with the digital multimeter. The course covers core electrical fundamentals including, electron theory, electromagnetism, electrical circuits, and basic formulas. Students will work through hands-on activities focused on series and parallel circuit construction, voltage drop measurement, and systematic diagnostic techniques, preparing them for advanced electrical coursework and the diagnosis and repair of alternatively fueled transit vehicles.

Course Duration

2-4 hours online over a 2-week period
