Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

Learners examine dew point and the two types of humidity values, absolute and relative, along with the types of instruments used to measure them. The activity includes a video clip and a quiz.

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.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

Identify whether the statement is an example of absolute or relative dating.
