Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.

In this learning activity you'll build a resistor's color code based on the bands.

In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.

In this animated object, learners examine the operation of a capacitive proximity sensor. A brief quiz completes the activity.

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

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Instructions on how to use and construct a truth table for digital devices are provided.

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

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