Electric current: the flow of electrons through a substance.

Electrocution: death as a result of exposure to electric current.

Electrical injury: Tissue damage as a result of exposure to electrical current.

Electrical burns: Thermal injury with tissue necrosis due to the heat generated by electrical current.

Electrical shock: The violent response to electric current exposure often characterised by involuntary muscle contraction.
