Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.

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.

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.

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 examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

Learners view animated scenes of problems caused when a lift truck is not operated properly. This object uses audio on some pages.
