Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
Series Motor Run-Away
By Terry Bartelt
Learners consider the changes inside a series motor that could cause it to break apart if the load was disconnected. A quiz completes the activity.
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Sensor Wiring Configurations
In this animated object, learners examine how two- three- and four-wire sourcing and sinking sensors operate. A brief quiz completes the activity.
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
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 RC Circuit Vector and Circuit Analyzer
Parallel RL Circuit Vector and Circuit Analyzer
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
You'll learn to identify frequency bands of the electromagnetic spectrum licensed by the FCC.
Radio Frequency Modulation
You'll learn some concepts related to radio frequency modulation.
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
