# Electric Machinery Fundamentals by Stephen Chapman By Stephen Chapman

Electrical equipment basics is still a best-selling equipment textual content because of its obtainable, student-friendly insurance of the real subject matters within the field.
In the 5th variation, using MATLAB® is still included in examples and difficulties, the place appropriate. The distinctive and thought-provoking difficulties youve come to understand were retained during this edition.
Chapman maintains to percentage his updated wisdom and reports within the box in an enticing and comprehensible type.
