Students solve problems on the determination of total inductive reactance of series-parallel inductors.
How Current Requires Voltage
By Terry Bartelt
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
Magnetics AC Power Generation
By Tim Tewalt, Patrick Hoppe
Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.
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.
Transistor AC Analysis Practice Problem: Circuit #4
By Patrick Hoppe
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
Series RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Parallel RL Circuit Vector and Circuit Analyzer
This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.
Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
