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
The electricity itself isn’t blue, per se. It’s the ionization of Nitrogen in the air that makes it look that way. When you burn metals or create a spark, you aren’t ionizing Nitrogen in the air, instead you are burning the material that caused the spark, which is going to burn a different color.
That’s about as ELI5 as I could get lol.
