Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.
Oscilloscope Frequency Measurements
By Terry Bartelt
Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
Sensitivity Adjustments of a Capacitive Sensor
In this animated object, learners study the effects of making sensitivity adjustments to a capacitive sensor.
Weight- Volume Relationships: Porosity
By Steve Whitmoyer
Students read how to determine and calculate the porosity for a given sample of soil or aggregate, based on the weight-volume relationship.
Resistance Temperature Detector (RTD)
Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
