Students read about the four steps to creating an ac model and view examples.
Opens Affecting Current in a Series Circuit
By Terry Bartelt
In this learning activity you'll review how an open in a series circuit affects current.
Excel: Converting Radians to Degrees
By Patrick Hoppe
Students read how to use the DEGREES() function to convert radians to degrees.
Inductive Reactance Demonstration 2
In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.
Voltage Measurements of a Half-Wave Rectifier
In this animated lesson, students view how an oscilloscope and a DC voltmeter measure the voltage of a half-wave rectifier.
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.
