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.

In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.

In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.

In this interactive object, learners use the Pythagorean Theorem to calculate forces.
