In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.

Learners view the steps for determining the square root of a complex number in Excel.

Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.

In this animated object, learners examine how two- three- and four-wire sourcing and sinking sensors operate. A brief quiz completes the activity.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

Students review the Voltage Divider Rule and work practice problems.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
