This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

Learners review the VDR and work six problems. Immediate feedback is given.

Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.

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.

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

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
