Cannot understand the static electric solution of touching a key first

98 viewsOtherPhysics

Hi. It’s Winter again and the static electric at my home is horrible. I already have a humidifier on and am wearing cotton clothing. I’m trying to find a solution and there’s recommendation to touch something metal first (e.g. a key) instead of being shocked by any metallic door handles — I don’t get it? wouldn’t I just be shocked by the key instead? Thanks.

The zap happens as you touch something. There is one point of contact where a lot of electricity flows. If you make good contact with, say, a key, and use *that* to touch doorknobs, then the spark happens between the key and the knob. Not your hand.
