This interactive presentation, created by Terry Bartelt for the Electromechanical Digital Library, discusses phase splitting in single-phase motors. Bartelt begins with a discussion of the sine waves that starts this process. After this important introduction, the author allows the student to...

Circuit Construction Kit adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.This simulation of a Circuit Construction Kit(AC+DC)is from the Physics Education Technology website of University of Colorado. Included are...

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them. This simulation of a Conductivity is from the Physics Education Technology website of University of Colorado....

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. This simulation of a Gas Properties is from the Physics Education...

Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.This simulation of a Resistance in a Wire is from the Physics Education Technology...

The interactive resource, presented by the University of Colorado, Boulder, presents a demonstration how a doped semiconductor to create a diode or transistor. Watch the electrons change position and energy. This interactive simulation has a teacher's guide and an ideas and activities section.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it. This simulation of a Signal Circuit is from the Physics Education Technology website of University of Colorado. Included are links...

In this video from the ICT Center, learn about fiber optic receivers. Investigate the components of an optical receiver; how a photodetector converts an optical signal to an electrical one; and the characteristics of PIN, avalanche, and metal-semiconductor-metal photodiodes. The video runs 2:07 and...

In this professional development video from Getting Results, natural resource technology instructors at a community college discuss fitting their courses together. The instructors say that clarifying and communicating outcomes helps them plan courses. They can reinforce skills taught across the...

In this media-rich, self-paced lesson, students explore the range of industries that produce and rely on advanced technology and learn how their skills and interests may align with career opportunities in this cutting-edge sector. The lesson contains videos that feature professionals describing...
