Learners read about how universities, government agencies, energy companies, and nanotech firms are working together to use nanotechnology to help produce clean water for consumption.
Op Amp Fundamentals: The Transresistance Amplifier
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.
Complex Power: The Sum of the Individual Real and Reactive Powers
The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
Explore what time management is, how to use a time matrix, and how to put it all together and use our new time management skills to accomplish more during your days.
Learners listen to effective techniques to successfully interact with customers via the telephone. They also submit their own suggested replies to customers in various scenarios. Topics include general telephone etiquette, dealing with angry callers, working with confused or unsure customers, and managing voicemail. A quiz completes this customer service activity.
The learner will gain an understanding of the inner workings of the cycloidal gear drive while watching a video and listening to an explanation of its features.
