In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Synchronous Speed of an AC Motor
By Terry Bartelt
In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.
The Eight Wastes of Lean
By Kaye Krueger
Learners examine ways to eliminate or minimize the wastes found in business processes. A matching exercise completes the activity.
Standard Calibration Procedure
Learners follow steps to calibrate a transmitter used in process control applications. A brief quiz completes the activity.
Sine Wave Fundamentals: Practice Problem #3
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.
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.
