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.
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.
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.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
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.
