This lab manual, created to accompany Introduction to Electric Circuits: Lab Manual, ninth edition, is suitable for introductory electric circuits courses offered through electrical technologist- and electrical technician-level programs at the college level (primarily those using Introduction to Electric Circuits: Lab Manual 9e). This text is also suitable for use in non-specialist survey courses at the university level. The manual contains a collection of experiments chosen to cover the main topics taught in foundational courses in electrical theory. Experiments can all be done with inexpensive test equipment and circuit components. Each lab concludes with questions to test students' comprehension of the theoretical concepts illustrated by the experimental results. The manual is formatted to enable it to double as a workbook, to allow students to answer questions directly in the lab manual if a formal lab write-up is not required.
