Full-Wave Rectifier
By Patrick Hoppe
Students examine the full-wave rectifier. They review appropriate formulas and examples of actual circuits.
Power Law: The Relationship of Voltage, Current, and Watts
Learners examine three formulas than can be used to find dc power. Examples are given.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Vector Diagram for a Series RL Circuit
Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.
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.
Air Flow In The Respiratory System
Put the parts of the respiratory system in the correct order of air flow from the outside to the inside of the body.
