In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

In this learning activity you'll explore the operation of frequency division using several different types of counters.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.
