Students view the parts and movements of a combustion engine in this animated activity. Each part is described.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

In this animated object, learners examine the parts of a pneumatic power system, including the prime mover, compressor, and receiver tank, and how they function.

Learners view animations showing the operation of the internal parts of an AC generator. A short quiz completes the activity.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.
