Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
Motor Control: Hands-on Testing and Troubleshooting Procedures for the Motor Control Lab
By Dick Dierks
Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.
Crank Rocker Velocity
By James Bourassa
In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.
By Terry Bartelt
In this animated activity, learners examine how residual magnetism causes magnetic hysteresis.
Finding the Common Connection of an SPDT Switch
In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.
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.
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.
You'll learn to identify antenna terms and concepts.
