Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

Learners read an explanation of how to troubleshoot a faulty digital-to-analog converter that has a shorted input.

In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.
