In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.

In this animated object, learners examine how to wire field devices to a PLC sinking input module.

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.
