Power = V x V / R

Power goes up as resistance is lowered.

 

I realized that the spark and white smoke are not visible in my original movie speed, so I had to specifically make them more visible in this later upload. Its a pity youtube does not let US re-upload over the original video.
Check at 5:13 and some slow timed smoke after that.
Practically its the exact movie as before, but with these details more slowed down.
