Electrical Systems Current (sv)
How does current work? Find out as this teacher from Dallas, Texas, helps you learn. This video is in lecture format - with the teacher speaking into the camera and a dry erase board behind her. She focuses much of her time on the formulas for currents and amps. Some key words include: matter, positive charge, negative charge, repel, attract, electron, coulombs, current, flow, and amp. Run time 04:00.
Electromagnetic Induction
After Oersted's 1820 discovery that electric currents create magnetism, it was obvious that in some way magnetism should be able to create electric currents. The discovery of electromagnetic induction, in 1831, by Michael Faraday and Joseph Henry was one of the most important of the 19th century, not only scientifically, but also technologically, because it is the means
Alternating Current
Electromagnetic induction makes it easy and natural to generate alternating current. Use of transformers makes it practical to distribute ac over long distances. Although Nikola Tesla understood all this, Thomas Edison chose not to, and thereby hangs a tale. Alternating current circuits obey a differential equation identical to the harmonic oscillator resonance equation
How Does a Solenoid Work?
A solenoid works by having electricity flow through its copper
wire that is provided by a power supply and a switch. Learn how a
solenoid becomes a magnet when electricity is supplied to it with
information from a science teacher in this video.
What Is an Electrical Inverter?
An electrical inverter is a device that can create an alternating
current from a direct current, allowing the current to go backwards and forwards instead of in only one direction. Find out how an electrical inverter works from a science teacher in this
video.

What The Liver Looks Like When You Drink Alcohol
Drinking alcohol causes liver cells to build up globules of
fat which turn into scar tissue on the liver. Learn how scar tissue
prohibits the liver from doing its job in this clip with information from a science teacher.

Draw an Isosceles Trapezoid
This video illustrates how to draw an isosceles trapezoid. This video is suitable for high school geometry students.
Line Segments
A line segment is part of a line, has fixed endpoints, and contains all of the points between the two endpoints. One of the most common building blocks of Geometry, line segments form the sides of polygons and appear in countless ways. Therefore, it is crucial to understand how to define and correctly label line segments. (01:18)

Solving Quadratic Equations by Graphing
The instructor in this video, Sal Khan, uses a graphing calculator to solve quadratic equations. Mr. Khan uses computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The viewer may want to open the video to 'full screen' as the instructor fits a lot of information on a dark screen.
