Learners view an animation showing the one-shot operation of a programmable logic controller.
Electrical Units, Abbreviations, and Symbols
By Patrick Hoppe
In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.
By Terry Bartelt
In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.
Statics - Trig: The Law of Cosines Using a TI-36X Calculator
By Steve Whitmoyer
Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.
Series Circuit Analysis Practice Problems: Circuit #8
In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
The schematic symbols of logic gates used in digital circuits are shown.
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.
Digital Circuit Devices
The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
You'll focus on terminology related to designing a hypothetical program.
