This primer introduces the student to the proper use of the exponent (EE) function on a TI-86 calculator.

Learners examine the conventional current flow at a PLC input module, along with the field devices connected to it. This interactive object includes quiz questions and feedback.

In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.

In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.

Learners view animations showing how hubs and switches work in local area network configurations.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
