In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Learners view a vector diagram for a series RC circuit and read information concerning the voltage across each component, the total voltage, and the phase angle.

Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

This animated guide presents an FAA map and aerial photos showing various areas of interest to student pilots enrolled in flight training at FVTC Aviation at Wittman Regional Airport in Oshkosh, WI. The airport is the site of the annual Experimental Aircraft Association's AirVenture Oshkosh. This object has sound.

In this interactive object, learners follow six steps for analyzing a process in a manufacturing setting. This activity includes a drag-and-drop exercise and textboxes where learners post their ideas.
