This video from Columbia Gorge Community College is part one of two videos where viewers "interpret manufacturer, mechanical, and electrical data from a pair of sample motor nameplates." An overview of motor nameplates and their purpose, electrical calculations, and mechanical calculations are...

This video from Columbia Gorge Community College is part two of two videos where viewers "interpret manufacturer, mechanical, and electrical data from a pair of sample motor nameplates." In this video, a Toshiba nameplate is highlighted. The video recording runs 6:54 minutes in length.

This animation of N-Channel Enhancement MOSFET Characteristic Curves is provided by Maricopa Advanced Technology Education Center (MATEC). The objective of the animation is to determine the active and non-active operation of regions of an n-Channel MOSFET gate. An .mp4 is also available and runs...

This animation shows band populations as a function of temperature in an n-type semiconductor. Note that the Fermi-energy actual shifts position in the band gap and is not accurately depicted here. The video shows the conduction bond and valence bond separated by a band gap where the donor electrons...

This tutorial is provided by National Instruments and introduces users to various types of sensors to acquire data. Topics covered include Sensor Terminology, Measuring Temperature with Thermocouples, Measuring Temperature with RTDs or Thermistors, Measuring Strain with Strain Gages, Measuring...

This lecture, published by Columbia Gorge Community College, provides an overview of the inefficiencies of non-ideal transformers. The objective of the lecture is to learn how to "examine efficiency and voltage regulation of non-ideal transformers. Explain copper losses, iron losses, and excitation...
