Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.
The IR Comp Network
By Terry Bartelt
In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.
Transistor Fundamentals: Base-Biased NPN Transistor
By Patrick Hoppe
Students view a dc analysis of a base-biased NPN transistor.
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.
The TI-86 Scientific Calculator: The Editing Functions
Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.
Capacitive Probe Sensors
Learners study the operation of capacitive probe sensors used to measure levels in a tank.
Conductive Probe Sensors
In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.
Displacement Level Sensors
In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.
In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
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.
