For those who wanna know.and who has experience it from me....
"Static electric" sparks can be irritating and their cause sometimes seems mysterious. If you scuff your feet on the carpet, you expect to be zapped by the next doorknob you touch. But why do our bodies sometimes become charged from simply walking around?Actually, no friction or rug-scuffing is required in order to electrically charge your body. The need for friction is a widespread misconception. While it's true that the friction can increase the charge-separation process, friction isn't the cause. Whenever two different insulating surfaces touch together, opposite charges within the two surfaces become separated. Simply walking across certain rugs or plastic flooring will cause your shoe soles to touch the dissimilar material of the rug. This is enough to separate the negatives from the positives and create imbalanced electric charges on the bottoms of your shoes.
"Static" electricity ( more correctly called "net electric charge" ) appears whenever the normal quantities of positive and negative electricity in a substance are not perfectly equal. Remember that everything is made of atoms, and atoms in turn are made of positive and negative electric charges. In other words, your body is just a collection of positive and negative electrical particles. Normally the positives cancel out the negatives, and everything behaves electrically "neutral." No mysterious sparking. But if you ever end up with more negative than positive, or with more positive than negative, then you have a charge-imbalance on your body. You will get zapped the next time you touch a large metal object.
Exactly how can this imbalance occur? Whenever we walk, the soles of our shoes steal some negative charge from the floor. We leave behind electrified positive footprints, and our bodies aquire an overall imbalance of negatives. (Or sometimes vice versa with the negative and positive, since polarity is determined by the type of shoe soles and the type of rug.) After many footsteps, our bodies attain a high level of electric charge and a high voltage. Body-voltage can easily rise to several thousand volts, and the next time you touch someone else... ZAP!, the imbalanced charge gets shared between you and the other person. The spark is painful because it's extremely hot. It drills into your skin like a white-hot needle, creating a microscopic burned area.
Don't fall asleep!we're nearly there.things you need or want to know!
How does a human body generate static electricity?There are many factors increasing static electricity generation, including:
1. Wearing certain clothing (including shirts, jackets, pants and shoes). Wool, rubber, fleece, vinyl and synthetic materials increase the effect.
2. Having a house without grounded outlets, or having a house with bad wiring
3. Walking a certain way. Shuffling and dragging one’s feet will increase electrostatic buildup.
The humidity of where one lives. The lower the humidity, the better the conditions are for static generation.
4. As well as general humidity, having unusually dry skin may increase the ability to store static electricity.
now you know...sorry peeps!you can't put the blame on me.haha.
