This learning object, created by Terry Bartelt of the Wisconsin Online Resource Center, provides information about impedance matching applications. "learners consider why an impedance matching transformer is needed to connect an antenna to a television."

This website includes a variety of animations explaining the mechanical workings of a variety of steam, Stirling and internal combustion engines. The animations may be paused, slowed or sped up. The animations are accompanied by additional text explaining how each engine works.

This interactive presentation, created by Terry Bartelt for the Electromechanical Digital Library, discusses the armature action of an AC motor. Bartelt begins by discussing how the armature and stator are pivotal in the conversion of electrical to mechanical energy, the beginning of the entire...

The North Carolina Community College System BioNetwork's interactive eLearning tools (IETs) are reusable chunks of training that can be deployed in a variety of courses or training programs. IETs are designed to enhance, not replace hands-on training. Learners are able to enter a hands-on lab...

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular simulation deals with Beer's Law: "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute...

This video recording, from Excelsior College, takes users through a blueprint simulation. The simulation involves "an electrician troubleshoot[ing] a defective compressor motor that will not start." Appropriate blueprints are selected "that must be referred to while performing the troubleshooting...

This video recording, from Excelsior College, takes users through a blueprint simulation. The simulation involves "an electrician troubleshoot[ing] a defective water pump that will not start." Appropriate blueprints are selected "that must be referred to while performing the troubleshooting steps."...

This animation, created by faculty at Dartmouth University, is a boost converter. The resource features other animations including buck and discontinuous converters. The site also depicts simple diode, bridge, and half-wave with cap rectifiers.

This interactive presentation, created by Terry Bartelt and hosted by the Electromechanical Digital Library, discusses the history and theory of Boyle's Law. The presentation offers two different variations of the concept. The first involves "a change in pressure exerted on a given quantity of gas...
