This page contains links to various "virtual instruments" that are intended to help the student become increasingly confident with several basic concepts and skills considered in most circuits courses -- some of these skills are developed in the lab.
The instruments are in various states of development and therefore, as with the other items posted on this site, use them at your own risk. While significant attempts have been made to ensure accuracy of posted materials and outputs of interactive apps, errors are to be expected. If you happen to experience an erroneous result, please describe the issue in an email sent to circuitanalysistutor at gmail dot com.
