How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
Current and Voltage Parameters of Digital Circuitry (Screencast)
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
