===Meaning===
'''Electrical charge''' is a [[Conservation of Charge|conserved]] quantity and a [[property]] of [[Subatomic Particle|particle]]s which allow them to interact via the [[Electromagnetic Interaction|electromagnetic interaction]].
 
===About Electrical Charge===
: The [[SI Unit]] of '''charge''' is the [[Coulomb]] (C).
: '''Charge''' is a [[scalar]] quantity as it has [[magnitude]] but does not have a direction.
: '''Charges''' create an [[Electrostatic Field|electrostatic field]] which affects other '''charged''' [[object]]s.
: '''Charge''' is a conserved quantity which means; "'''Charge''' cannot be created or destroyed, it can only be transferred from one place to another."
: A flow of '''charge''' is an [[Electrical Current|electrical current]].
===About Electrical Charge at the Particle Level===
: '''Charged''' [[Subatomic Particle|particles]] may exchange virtual [[photon]]s causing a change in their [[momentum]]. This results in the [[force]] of [[attract]]ion or [[repel|repulsion]] between '''charged''' [[Subatomic Particle|particles]].
: As a [[Conservation of Charge|conserved quantity]] '''charge''' cannot be created or destroyed, but it can be transferred from one [[Subatomic Particle|particle]] to another. This occurs in the [[Weak Nuclear Interaction|weak interaction]] via the [[W-boson]].
: The [[Electrical Charge|electrical charge]] passed between [[Subatomic Particle|subatomic particles]] during the [[Weak Nuclear Interaction|weak interaction]] has a [[magnitude]] of 1.60x10<sup>-19</sup> [[Coulomb]]s (the [[Elementary Charge|elementary charge]].
: The [[Electrical Charge|electrical charge]] of the [[proton]] is +1.60x10<sup>-19</sup> [[Coulomb]]s and the [[Electrical Charge|electrical charge]] of the [[electron]] is -1.60x10<sup>-19</sup> [[Coulomb]]s.
