In this animated object, learners examine how the purge pressure system is used to measure levels of material. A brief quiz completes the activity.

In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

The learner will understand the operation of the six fundamental logic gates and the inverter by using truth tables, Boolean Algebra equations, switch analogies, and written statements.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

In this module, you'll build upon the concepts Understanding and Writing Pseudocode: The Basics, by learning new techniques and terms to make your pseudocode more complete.
