Wire
,no edit summary
===About Wires===
: '''Wires''' are used to connect [[Electrical Component|electrical components ]] together.
: Electricity flows through the metal in the '''wires'''.
: A '''wire''' is usually covered in [[Plastic (Material)|plastic ]] for safety. The [[Plastic (Material)|plastic ]] is safe to touch, but if you can see the metal then it is dangerous and could electrocute you if you touched it.
: '''Wires''' come in many sizes. The thicker the wire the more electricity it carries and the more dangerous it is.
: The [[metal]] inside a '''wire''' is an [[Electrical Conductor|electrical conductor]] which means electricity can pass through it easily.
: The [[plastic]] covering the '''wire''' is an [[Electrical Insulator|electrical insulator]] which means electricity does not pass through it very easily.
==Key Stage 3==
===Meaning===
A '''wire''' is a long, thin piece of [[metal]] that allows electricity through it.
===About Wires===
: '''Wires''' are used to connect [[Electrical Component|electrical components]] together.
: [[Electron]]s flow through the [[metal]] in the '''wires''' as an [[Electrical Current|electrical current]].
: A '''wire''' is usually covered in an [[Electrical Insulator|insulator]] such as [[Plastic (Material)|plastic]]. This prevents [[Electrical Current|electrical current]] leaving the [[wire]] when it is touched by an [[Electrical Conductor|electrical conductor]]. This also prevents [[electrocution]].

: [[Wire]]s are [[heated]] by an [[Electrical Current|electrical current]] passing through them.
: [[Wire]]s are designed to be a low [[Electrical Resistance|resistance]] in order to allow an [[Electrical Current|electrical current]] through them without losing [[energy]] too much [[energy]] by [[heating]] the [[wire]]s.
