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.
The Ideal Bode Plot
By Patrick Hoppe
The Ideal Bode plot is introduced. The three main topics covered are: corner frequencies, midband voltage gain, and the roll-off rate.
By Terry Bartelt
Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.
Testing an On/Off Switch
In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
Power Calculations in a Series/Parallel Circuit
In this learning activity you'll explore various ways to calculate the power consumed in a series/parallel circuit.
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 antenna terms and concepts.
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
You'll learn to identify frequency bands of the electromagnetic spectrum licensed by the FCC.
