Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
Strength of Materials: The Centroid of a Semicircle
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a semicircle.
By John Casey, Terry Bartelt
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
Pressure Relief Valves
By Terry Bartelt
In this animated object, learners examine the operation of a hydraulic relief valve and its internal components. A brief quiz completes the activity.
RPM of AC Motors
By Terry Bartelt, Terry Fleischman
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
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.
Oscilloscope Phase Shift Measurements
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Energizing Time Constants of an RL Circuit
In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.
De-Energizing Time Constants of an RL Circuit
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
