Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

Learners examine the basic elements of a machine vision system. A short quiz completes the activity.

Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.

Learners practice revising poorly written directions by applying criteria for giving directions.

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.

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

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.
