Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Gear Ratio Concepts
By James Bourassa
In this animated object, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations. A quiz completes the activity.
The Inductive Kick of an Inductor
By Terry Bartelt
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
Kirchhoff's Current Law: Practice Problems
Learners review Kirchhoff's Current Law and work six practice problems. Feedback is given.
Voltage Drops in a Series Circuit
Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.
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.
Series RL Circuit Vector and Circuit Analyzer
Parallel RC 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 frequency bands of the electromagnetic spectrum licensed by the FCC.
You'll learn to identify antenna terms and concepts.
Radio Frequency Modulation
You'll learn some concepts related to radio frequency modulation.
