In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Gear Ratio Concepts (Screencast)
By James Bourassa
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
The Variable Reluctance Stepper Motor
By Terry Bartelt
Learners view colorful animations showing the operation of a VR stepper motor.
Voltage and Resistors
By Tim Tewalt
This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.
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.
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 RC Circuit Vector and Circuit Analyzer
Parallel RL Circuit Vector and Circuit Analyzer
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
