Answer:-
Electrocautery Device
Explanation:-
The heat and light produced like a discharge due to a low impedence connection is called arc flash. They can cause substantial damage including fire and injury.
Electrocauterization or electric surgery is the process of destroying tissue with electricity. In this process the electrode is held away from the tissue, so that when the air gap between the electrode and the tissue is ionized leading to an electric arc discharge.
Here a low impedence is used to since a return electrode burn will occur if the heat produced, over time, is not safely dissipated by the size or conductivity of the patient return electrode.
Hence an arc flash can result from a Electrocautery Device if proper precautions are not taken.
