Driving down the road yesterday they were repairing some electrical lines and I guess one of them sparked and it left a trail of blue sparks on the ground. But when I hook up a battery and short it with a wire sparks appear an orangish-yellow color.
Anyone know why?
In: Engineering
Electricity is actually invisible. When it arcs through the air, it ionises the gasses, and since the air is mostly nitrogen, and nitrogen ionises violet, lightning and sparks appear blue.
If the sparks were travelling through a different gas, they would be a different color.
