Current and Voltage Parameters of Digital Circuitry

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.

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.

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.

Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-30XIIS Calculator)

Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.

Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.

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.
