This course covers principles of DC (Direct Current) electricity in a simple, easy to understand, format. It is themed after a book published by the instructor, titled: “Electrical Engineering for non-Electrical Engineers.”  Prof. Rauf uses simple analogies and practical, day to day, examples to illustrate the, otherwise, abstract concepts of DC electricity. Upon attending this course, participants will be able to perform straightforward and common calculations, in the DC realm, associated with voltage, current, resistance, circuit analysis, power, service factor, and much more. 

Practical examples of DC electrical equipment applications, in industrial, and institutional settings are covered. This includes discussion on DC power transmission systems, solar PV systems, EV’s (Electric Vehicles), LED’s, DC ESS (Energy Storage Systems), HESS, DC-DC converters, DC mining dragline equipment, Diesel locomotives, etc. Applications of electronic DC safety devices are explained and illustrated. A few DC articles in the National Electrical Code are introduced. This course is designed for engineers, professional engineers, energy professionals, engineering managers, technical professionals, facilities managers and other professionals who are not intimately familiar DC principles, practices and applications. Audience is engaged through Q&A, classwork, and ad hoc discussions pertaining to the topic.

2. You will learn about the differences between DC and AC power transmission systems.

3. You will learn about DC based electrical energy production (PV) and Energy Storage Systems i.e., batteries and supercapacitors.

4. You will get introduced to myriad DC technologies and equipment and gain appreciation of how ubiquitous and indispensable DC is in our personal and professional lives.

5. You gain familiarity with DC power distribution equipment and instrumentation.

6. You will understand the role NEC, and NFPA 70 E, play in the realm of DC electrical design, electrical safety and arc flash hazard.

7. You will learn how to interpret DC electrical one-line and control diagrams.
