Learners examine the counter-reset function of a programmable controller and how it is used.
AC Voltage Conversions
By Terry Bartelt
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
Calculating Belt Velocity and Horsepower
By James Bourassa, John Rosz
In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.
Series-Parallel Circuit Analysis: Practice Problems Circuit 1
By Patrick Hoppe
In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.
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.
