In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.

In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.

Students read an introduction to the electronic workbench and view a demonstration of how to open a file for circuit simulation.

The schematic symbols of logic gates used in digital circuits are shown.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
