A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle. A "transformer" only changes one voltage to another; it doesn't change power levels. If you put 100 watts into a transformer, 100 watts come out the other end. [Actually, there are minor losses in the transformer because nothing in the real world is 100% perfect. But transformers come pretty darn close; perhaps 95% efficient].
This course provides you with insight to the fundamentals and applications of transformers.
This 3-hr course material is based entirely on Naval Education and Training Materials (NAVEDTRA 14174), Electricity and Electronic Training Series; Module-2, Chapter 5, titled “Transformers”.
The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
