Zapping someone with your finger is sure to elicit a lot of joke when you ’re 11 , but static electricity is one of those things that lose its magic with long time . After all , it ’s the nemesis of good hair days and , if you have computed axial tomography , they probably do n’t prize getting shocked whenever you pet them ( sorry , Fluffy ) . So how exactly is static electrical energy produce , and why does it seem to occur more oft in the winter ?
To hark back to a high schooling science lesson : Static electricity is created when there ’s animbalancebetween the positive and damaging charges of two objects . Most of the object you use on a day-to-day basis are electrically neutral . In other Book , the proton ( positive charge ) and electrons ( negative bearing ) that make up their corpuscle poise each other out , and no one get appalled . However , the outer negatron in an atom can move around more freely than proton , and sometimes they pass over from one open to another when two fabric come into tangency .
This often hap when clash is involved . A classic example of this is when you shuffle across a wool carpet while assume pencil eraser - resole shoes . Wool — like pencil eraser , wood , crank , credit card , and pelt — is an dielectric . This means that the electrons in woollen are more tightly constipate to the atom and are improbable to agitate . Since gumshoe and wool are both insulating cloth , an even stronger electrical direction is likely to progress up in your body , Lifehackerexplains .
Essentially , one physical object becomes more positively charge because it does n’t have enough protons , while the other one becomes more negatively charge because it has too many negatron . If one of those charged object — like you — were to affect a director , like a metal doorknob , then the cathexis would be neutralize . This release is what make a blow , or static discharge . It ’s all part of nature ’s attempt to restore order and balance .
That brings us to the second part of the doubtfulness . The reason static electrical energy is more common in the wintertime is because the air humidity is low-down . The juiceless air travel is less conductive , leave in more powerful zaps . TheMoon and Mars , for example , are especially wry surround , so next astronauts ( or colonizer ) should take measure to avoid shock their electronic equipment . Although inactive electricity is commonly harmless , under just theright conditionsit can make inflammable substances to ignite or explode , and it can also be harmful to electronics .
It is n’t all spoilt , though . A controlled phase oftriboelectric charging , as static direction are also known , is the technology behind copiers and laser printing machine . The key is knowing how to control it — and there are a few trick you could try at base to thin your vulnerability to unpleasant shocks .
If you desire to pet yourcatwithout zapping her , dip your fingers in water first . This will facilitate remove the charge from static electricity so you do n’t pass it to along to your unsuspicious fur babe . Humidifiers also help by releasing more moisture into the air and making it more conductive . Lifehacker also recommends swapping out your rubber - soled shoes for leather ones ( or just go barefooted ) , and avoid wool socks and jumper .
