Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Weight- Volume Relationships: Saturated Density (Metric)
By Steve Whitmoyer
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
Synchronous Speed of an AC Motor
By Terry Bartelt
In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.
Series RL Circuit Practice Problems
By James Bourassa, John Rosz
Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
Ohm's Law: Current
By Tim Tewalt, Patrick Hoppe
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
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.
The Logic Gates
By Patrick Hoppe
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
