This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

Learners study the method of cascading two or more PLC timers to extend their time capacity.

In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.

In this animated activity, students examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

In this animated object, learners examine the operation of various circuits that are internal to the inductive proximity sensor.

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.
