In this animated activity, students view a step-by-step approach of how to connect an ammeter to a circuit. A brief quiz concludes the lesson.

Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.

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

Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.

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.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.
