Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
By Terry Bartelt
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.
Internal Elements of a 555 Timer
In this highly interactive object, learners examine the internal elements of a 555 IC and their operation. Learners then test their knowledge in a variety of exercises.
This learning activity describes the abilities of an inductor coil to oppose alternating current and to pass direct current.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
Measuring Length in the Metric System
By Nabila Dahche
In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.
How to Convert from One Unit to Another in the Metric System
In this learning activity you'll practice converting from one metric unit to another.
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.
By Terry Fleischman
In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.
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.
