Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
GD&T: Geometric Characteristic Symbols
By Glenn Sokolowski
In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
By Terry Bartelt
Learners study how a DC motor generates counterelectromotive force. A short quiz completes the object.
Sine Wave Fundamentals: Practice Problem #8
By Patrick Hoppe
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
Crank Slider Velocity
By James Bourassa
In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.
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.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
The Reflected Load in a Transformer
Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.
Transformer Action Demonstration
Learners view animations and video clips showing how power is transmitted from one energized coil to another.
