Order process, wrong answer.02/16/2021 ByJeannette Beebe The order process was great. I received my purchase shortly after. I did, however, find a wrong answer on one of the electrical questions. Chapter 12, page 12-5, question 12-17. The answer indicates that the variable resistor is answer A and I know that to be an iron core transformer. My instructor confirmed this. Our responseWe will review that question and answer and make the proper adjustments. Thank you for your review.
