In this learning activity you'll explore the functions and proper operation of a digital multimeter.
Kirchhoff's Current Law
By Tim Tewalt, Patrick Hoppe
Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
Deriving the Formulas of the Power Wheel
By Ron Wallberg
Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.
By Terry Bartelt
In this animated activity, learners examine how residual magnetism causes magnetic hysteresis.
The TI-83 Plus Calculator: Using the Exponent Function
By Patrick Hoppe
This primer introduces the student to the proper use of the "EE" function to perform calculations on very large or very small numbers.
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.
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.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
