In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.

Learners read how to use the arctangent function to calculate the theta of an angle. The proper keystrokes are displayed.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.

Students answer five questions concerning magnetism.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current and power. A help screen is provided.

This game is to help students review the vocabulary words for our industry test.
