Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Oscilloscope Frequency Measurements
By Terry Bartelt
Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Weight-Volume Relationships: Density
By Steve Whitmoyer
Students read an explanation of the use of weight-volume relationships and practice calculating density.
Series RL Circuit Vector and Circuit Analyzer
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Parallel RL Circuit Vector and Circuit Analyzer
This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.
Capacitive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.
Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
