Why do people get shocked in winter (especially) when walking on wooden floors?
Static electric builds up any time you rub two dissimilar materials together where you have one that has two many electrons accumulated on it caused by the friction that strips electrons from one surface. In the summer time you have lots of humidity in the air which also fills all the materials around the room with excess humidity (that’s why wooden doors stick in the summertime but not the winter) Static electricity always resides on the very surface of the materials that made it, so it goes from your shoes to your skin surface giving you a negative charge. The humidity permeates the door material slightly and the moisture from the air mixes slightly with the wood of the door and dissolves a little bit of ions into the water at the surface. Water by itself is not a conductor, but when it gets contaminated by the wood door, it will conduct electricity. In addition, the carpet has absorbed moisture from the air and it also has ions from dirt contamination of the humidity water. So in th
