Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Opens and Shorts
By Terry Bartelt
In this animated activity, students examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.
The Function Generator
Students read a description of the function generator and view a graphic that labels its parts.
Hydraulic Pump Action
By Terry Bartelt, Stephen Schneider
Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.
Mathematical Expression of an AC Sine Wave
By Patrick Hoppe
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
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.
Learners observe animations showing how data is converted between serial and parallel flow.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
