The Direct Current Fundamentals provides a thorough exploration of DC electricity, combining both theoretical foundations and practical applications. The book begins with basic electrical concepts such as electrons, current, voltage, and resistance, then progresses to the analysis of series, parallel, and series-parallel circuits. Key electrical laws—including Ohm’s Law and Kirchhoff’s Laws—are explained and applied throughout, ensuring students understand both the principles and their real-world relevance. The text also covers DC machines, including motors and generators, as well as magnetic effects of current and their applications in DC systems. Each chapter includes worked examples, problem sets, and illustrations to reinforce understanding, while energy efficiency and “green” practices are integrated to emphasize modern electrical considerations. Overall, it serves as a comprehensive resource for learners preparing for electrical certification or entering the electrical trade.
