Electricity: getting a shock from the car
The tutor shares some research about why he gets shocked leaving the car.
When the weather turns dry and summery, I love it. However, I face a summertime hazard: getting an electric shock when I leave the car. Sometimes the shock makes me wince as I hear the “crack”.
Last night I researched the reason for these shocks. Possibly, it’s mundane: as my leather belt and even my dry skin rub against the polyester seat, they develop positive charge (the seat, negative). When I touch the metal door, my positive charge attracts electrons through my fingers – zap! In dry weather, the process is emphasized, since there is less water to bleed away static charge.
I’ll be talking more about static electricity:)
