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

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.

The learner will...be able to safely use grinding equipment in the welding and metal fabrication shop.

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

This general shop safety test assesses the student's knowledge of acceptable safety practices associated with the machine shop.

In this learning activity you'll review the safety considerations for persons using the power pinch roller and take a short quiz.

Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.

In this learning activity you'll review safety considerations for using hydraulic press brakes.

In this activity you'll identify several hazards in a welding environment.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.

In this learning object you'll view a list of ways to keep the area around the machine shop safe.

The student takes a 14-question quiz of shop safety.

This text document lists 27 safety items to consider in a machine shop.

Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.

In this learning activity you'll review rigging and lifting as well as signals for crane movement.

Learners rank the most efficient ways in which workers retain information and create their own plan for improvement.

In this learning activity you'll review safety considerations for persons using a hydraulic iron worker and takes a short quiz.

In this learning activity you'll review the safety equipment used to protect a worker's face and ears.
