Students view the formulas to be used to convert a parallel impedance to a series impedance.
The Semiconductor Diode
By Terry Bartelt
In this interactive object, learners examine the PN sections of a diode and the diode's forward- and reverse-biased operations. A brief quiz completes the activity.
Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.
Parallel RC 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.
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.
Inductive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
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.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
