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))
