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 blue or purple is superheated air letting of photons because the air cant hold that much energy. The sparks are usually the ends of the wires melting off because of the arc. Superheats the end till it melts and increases in resistance and then they boil off and that’s the spark you see. It’s all happening extremely quickly though.
