In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.

In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.

This presentation will aid beginning students in correctly using a DVOM. It will give them informatin on symbols and basic hook-up information.

Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.

Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.

In this animated object, learners examine why and when the Kelvin scale is used. A brief quiz completes the activity.

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.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales. A short quiz completes the learning object.

Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
