Learners examine the counter-reset function of a programmable controller and how it is used.
Excel: Complex Division
By Patrick Hoppe
Students view the steps for dividing complex numbers in Excel.
Transistor DC Analysis Practice Problems: Circuit #3
Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.
Pressure Measurements in Inches of Water Column
By Terry Bartelt
Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.
Statics: Force Systems
By Steve Whitmoyer
Learners read an introduction to the four basic types of force systems for a statically determinate condition.
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.
