In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
Learners examine the operation of an orifice plate flowmeter as it is used to make process control measurements. A brief quiz completes the activity.
