In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.

Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.

In this screencast, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

In this animated object, learners examine the structure and function of intracellular and extracellular fluid. They also read about the most common electrolytes in the body and complete a matching exercise to test their knowledge.

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

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
