In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.

In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

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.
