Learners examine the counter-reset function of a programmable controller and how it is used.
Op Amp Fundamentals: The Summing Amplifier
By Patrick Hoppe
Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.
Parallel RC Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.
Strength of Materials: The Centroid of a Quadrant
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a quadrant.
Feedback System Application
By Terry Bartelt
In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
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.
