Learners observe how to cascade PLC counters to extend the maximum count of one counter.
How Adding Parallel Branches Decreases Total Resistance
By Terry Bartelt
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
Instantaneous Voltage Calculations of a Charging RC Circuit (Calculator TI-30XIIS)
Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a charging RC circuit.
Optical Encoder Classifications
In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.
Quality Basics: The Scatter Plot
By Mary Lee Rudnick-Kaun
In this learning activity you'll review independent and dependent variables and view a demonstration of the positive and negative correlation.
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.
