FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
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.

Lightning's abrupt electric discharge is accompanied by the emission of light.
Static electricity — Class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltages of sufficient magnitude to produce visible attraction (eg., static cling), repulsion, and sparks.
Electrical conduction is an electricalphenomenon where a material (solid or otherwise) contains movable particles with electric charge, which can carry electricity.
When a difference of electrical potential is placed across a conductor, its movable charges flow, and an electric current appears.
Electrical conductivity may be represented by the Greek letters κ, σ or γ.
