In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.

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

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this learning activity you'll create a packet filter.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.

Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.

Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
