Learners examine the operation of various circuits that are internal to the capacitive proximity sensor.

Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.

Learners view an animated demonstration of how to determine the final output of the combinational circuit.

In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees

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.
