Petruzella's Computer Simulation Lab Manual with MultiSim CD can be used in conjunction with the author's Electricity for the Trades text, or as a stand-alone item. The Lab Manual contains simulation activities for all major topics in DC and AC electricity, and the experiments can easily be modified to use as physical labs with actual hardware.Students simply open the files on the accompanying CD, perform the lab (as outlined in the manual), and record their answers in the space provided. Nothing could be easier for the instructor and student. All labs have been field tested. Sure to maximize the use of the many MultiSIM installations out there.
