Description:
This basic book on electricity, magnetism, and dc and ac circuits combines understandable explanations with clear illustrations to make the theory interesting and easy to understand. As a result, it is the perfect introduction to the field for readers with no previous exposure to electrical studies, and an excellent refresher for those with electrical knowledge.
Beginning with fundamental concepts, the full spectrum of electric circuit topics is covered in non-intimidating fashion, from simple dc circuits to complex ac network analysis, including resonance, transformers, and three-phase ac circuits.
Excellent, informatively-captioned, illustrations help students under-stand each new concept or analysis method. Early coverage includes how to use electrical instruments (digital and analog), and a later chapter treats the application of an oscilloscope for ac waveform study.
The final chapters introduce computer analysis methods, showing PSpice and BASIC programs for analysis of problems given in examples throughout the text.
Features include:
- Objectives list at the beginning of each chapter.
- Step-by-step analysis procedures listed for every type of electrical circuit.
- Numerous practical worked examples.
- Practice Problems at the end of each section.
- Summary of formulas at chapter ends.
- Chapter Review Questions and Problems grouped and identified by section.
- Answers for odd-numbered problems at the back of the book.
- Unit definitions, standard component values, and more in the appendices.
