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.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

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

Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.

In this animated learning object, students read about the operation of a half-wave rectifier.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
