In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.

In this learning activity you'll outline a conversation using the transactional communication model. The print and Email function has been disabled. You may take a screenshot of the last screen if needed.

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 activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

In this animated activity, learners follow a step-by-step approach for connecting a digital multimeter to measure resistance. A brief quiz completes the activity.

In this animated object, learners examine the operation of up-counters and down-counters for a programmable controller. A brief quiz completes the activity.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

In this learning activity you'll define psychological noise and will complete an activity.

In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.

In this animated activity, learners read and listen to a dialogue in Mandarin Chinese in a grocery store setting. The learner can then click on photos of fruits and vegetables to hear their pronunciation in Mandarin.

In this animated object, learners examine how a Hall-effect sensor operates. A short quiz completes the activity.

In this animated activity, learners examine procedures in a doctor blade metering system.

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.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

In this animated activity, students view how the Wheatstone bridge is used to activate a temperature alarm. A short quiz completes the lesson.

In this animated object, learners examine how two- three- and four-wire sourcing and sinking sensors operate. A brief quiz completes the activity.
