Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Reversing the Rotation of DC Motors
By Terry Bartelt, Terry Fleischman
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
Statics - Trig: Pythagorean Theorem Calculations Using a TI-86
By Steve Whitmoyer
In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-36X Calculator)
By Terry Bartelt
Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
Analyze a Part Drawing
By Glenn Sokolowski
In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.
An Inductor Opposing a Current Change
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.
The schematic symbols of logic gates used in digital circuits are shown.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
Logic State Signals
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.
You'll focus on terminology related to designing a hypothetical program.
