The schematic symbols of logic gates used in digital circuits are shown.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Voltage and Current Amplitudes in a Series RLC Circuit
Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.
Pressure-Reducing Valve Application
By Terry Bartelt, Stephen Schneider
In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
Selecting a Proper Single Phase Transformer
By Gary Lindell, Terry Bartelt
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
Total Resistance of a Series Circuit
By Patrick Hoppe
In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.
PLC Shift Registers
By Terry Bartelt, Tom Yapp
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
The Three-Phase AC Generator
By Terry Fleischman
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
Current in a Series Circuit
In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.
Pneumatic Schematic Symbol Flashcards
This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.
