This video, provided by Columbia Gorge Community College, is the second part of a two part lecture that discusses period and frequency. The main objective of this lesson is to "define period and frequency [and to] learn to evaluate sinusoidal functions with respect to time." This video runs 10:04...

This experiment will demonstrate the effects of changes in the crystal structure of metals, particularly in high carbon steels and in the shape memory alloy Nitinol. Students will learn the effects of phase changes on shape in Nitinol and crystal structure changes on metal properties. They will also...

This tutorial is provided by National Instruments and includes information on phase-locked loops. "A phase-locked loop (PLL) is a feedback control circuit that synchronizes the phase of a generated signal with that of a reference signal." This tutorial includes a table of contents and the following...

Description: This learning module is provided by Work-Ready Electronics and covers phase-locked loops. Work-Ready Electronics modules are intended to be used either independently or integrated with current electronics curricula in college programs. This module is divided into three sections:...

This interactive presentation, created by Terry Bartelt for the Electromechanical Digital Library, discusses phase splitting in single-phase motors. Bartelt begins with a discussion of the sine waves that starts this process. After this important introduction, the author allows the student to...

This animation, created by Mahmoud Riaz of the University of Minnesota, presents an example in motion of an induction motor. As Riaz writes, "The steady-state characteristics of an induction motor are described by means of phasors, which are computed using the standard equivalent circuit and are...
