Less Text, More Action

Circuits (Algebra) teaches the basics of linear circuit analysis using algebra. Topics in the book cover the range of material typical of introductory circuits courses and were curated based on the syllabi of linear circuit analysis courses from the top 10 universities which graduated the most number of electrical engineering students in 2015.

  • Approximately 100 animations help students “see” the concepts and build an intuitive understanding
  • Over 500 interactive learning questions help students understand topics through incremental steps, keeping students engaged and providing thorough explanations of both right and wrong answers
  • Auto-generated and auto-graded Challenge Activities distributed throughout

What is a zyBook?

Circuits (Algebra) is a web-native, interactive zyBook that helps students visualize concepts to learn faster and more effectively than with a traditional textbook. (Check out our research.)

Since 2012, over 1,200 universities and colleges across the country have adopted web-native zyBooks to transform their STEM education.

zyBooks benefit both students and instructors:

  • Instructor benefits
  • Customize your course by reorganizing existing content or adding your own
  • Robust reporting gives you insight into students’ progress, reading and participation
  • Continuous publication model automatically updates your course with the latest content and technologies
  • Student benefits
  • Learning questions and other content serve as an interactive form of reading
  • Concepts come to life through extensive animations embedded into the interactive content
  • Save chapters as PDFs to reference the material at any time
