Learners examine the operation of an orifice plate flowmeter as it is used to make process control measurements. A brief quiz completes the activity.

In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.

Learners read how the transfer function for a RL 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 animated object, learners examine the operation of a temperature alarm circuit that uses a thermistor in a Wheatstone Bridge.

In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.

This learning object introduces the three approximations of a diode.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.

This primer introduces the student to the key terms and concepts associated with the silicon diode.

Learners view the operation of a full-wave rectifier which has two diodes.
