Electrical phenomenon - Definition and Overview

Electrical phenomena are commonplace and unusual events that can be observed which illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary division of electromagnetic phenomena.

Some examples are:

• Electroluminescence
• Electrical conduction
• Elves [1] (http://www.nytimes.com/2003/01/21/science/21SHUT.html?todaysheadlines)
• Ferroelectric effect
• Photoconductivity
• Piezoelectric effect
• Galvanic current generated by two different metals in contact
• Photoelectric effect
• Pyroelectric effect
• Sprites [2] (http://www.nytimes.com/2003/01/21/science/21SHUT.html?todaysheadlines)
• Static electricity static cling
• Sparks and lightning
• Telluric currents
• Triboelectric effect (materials which develop a charge when rubbed)
• Whistlers (radio waves produced by lightning [3] (http://www.altair.org/natradio.htm))
