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

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

The learner will identify the types of motion instructions used for programming a robot.

In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.

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.

Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.

Students read about the concept of true power and view examples of how it is dissipated as heat is provided.

Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.

Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
