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...

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change. This simulation of a battery-resistor circuit is from the physics...

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...

This learning object covers cylinders and motor pneumatic actuators. It is hosted by the University of Wisconsin-Madison and consists of cylinders operations such as: single, duel acting, factors for cylinder speed. The program require Macromedia Flash player, and presents a very nice overall...

This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty members Terry Bartelt and Stephen Schneider, introduces pneumatic air conservation. The lesson begins with an illustration comparing production of air force by electric and pneumatic...
