Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.

Learners observe how to cascade PLC counters to extend the maximum count of one counter.

Learners consider the changes inside a series motor that could cause it to break apart if the load was disconnected. A quiz completes the activity.

Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.

Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
