A short circuit, as shown in this next video, does not have a load providing resistance. The arc
that forms goes right through the air with little‐to‐no resistance.
The same thing happens in an arc flash. The circuit is completed straight through the air.
Select whether the following refer to a safely completed circuit or a short circuit that could lead
to an arc flash

Turning on a light in an office
Starting a motor control device
