In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.

In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

In this learning activity you'll review how an open in a series circuit affects current.

Learners read about a process for sorting items in the workplace. "Sort" is the first of the five steps in 5S.

In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
