Caption: Electrical discharge in air. Clip showing a close-up of the electrical discharge (corona discharge, purple spark) that occurs in air if the voltage is high enough to trigger sparking. This only occurs if the gas contains molecules that can be ionised with the voltage present. For the use of the gas sulphur hexafluoride (SF6) to stop the discharge, see clip K004/5564.
