Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
The Magnetic Circuit
By Terry Bartelt
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
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.
Interpreting Engineering Drawings: Common Abbreviations
By Glenn Sokolowski
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
Three-Phase Delta Transformer Calculations
By James Bourassa
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete 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.
Inductive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Parallel RC Circuit Vector and Circuit Analyzer
Parallel RL Circuit Vector and Circuit Analyzer
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.
You'll learn to identify antenna terms and concepts.
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
Radio Frequency Modulation
You'll learn some concepts related to radio frequency modulation.
