Learners read about the process of dividing industrial goods into the categories of entering, foundation, and facilitating.

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.

Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.

This learning object describes the equipment and supplies needed to document bloodstain patterns.

Learners consider the steps and supplies to use when diapering infants and toddlers. The proper diapering procedure not only meets basic care and sanitation needs but builds relationships and promotes the child’s learning. Brief quizzes complete the learning object.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
