In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
The Open-Collector Logic Device
By Terry Bartelt
In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.
Current Divider Rule (CDR)
By Patrick Hoppe
Students review the Current Divider Rule (CDR) and work practice problems.
Pulse Train Fundamentals: Practice Problem #4
In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.
Current and Voltage Parameters of Digital Circuitry
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
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.
