In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.

This learning object introduces the student to the calculations involved in a sieve analysis -- including percentage retained and percentage passed.

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 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.
