Thermistor Temperature Alarm Circuits
In this animated object, learners examine the operation of a temperature alarm circuit that uses a thermistor in a Wheatstone Bridge.
Analog Ammeter Operation
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
Resistor Color Code Description
By Patrick Hoppe
In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
Capacitor Values
In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
The Time-of-Flight Flowmeter
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
Ultrasonic Flowmeters
By John Casey, Terry Bartelt
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.
The Reynolds Number
In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).
Critical Position
By James Bourassa
In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.
The Hydraulic Pressure Switch
This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.
