Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.

Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

The learner views animation showing how a DC motor is wired and its operational characteristics. A short quiz completes the activity.

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

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Students use algebra to rearrange formulas and solve for the missing volume, density, or mass quantity.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Learners observe animations showing how data is converted between serial and parallel flow.

This game will give you practice with the computation skills you need for ratios, proportions, and measurement conversions.
