What are advantages of static electricity?

Static Electricity

  • Static electricity is usually a 'high voltage' but low power form of electricity. You can experience it by getting a shock when touching a door knob (winter time, dry cold air, walking across a carpet) or seeing socks clinging to other clothes in a dryer. While static electricity can easily destroy miniature electronics, it is a major component in making copiers and laser printers work. Other forms of electricity typically have much greater power capabilities and can be just as useful or destructive.
  • Lightning is static electricity, and it can damage buildings and harm people.
  • The disadvantages of static electricity would be that it is quite unpleasant if you get a shock. I think the advantages would be that it could help scientists to make progress in their 'inventions' or 'studies'. Also it is quite a lot of fun! I love doing experiments in class with static electricity and making bits of paper stick to my ruler. (NB. I am only 12)
  • One disadvantage I think it be is that you could get a shock and it could hurt.(Ouch!) Another disadvantage is that if you take off your hat in winter time and you have long hair (which I have), your hair will be sticking up very badly. One advantage is that you could do cool experiments with static electricity like make water bend, make cereal fly, and other cool stuff. You could also get a shock which might hurt but personally I don't think it hurts, I think it's cool. Another advantage is that in summer, if you take off your hat and you have long hair, you don't get static because in summer it isn't that humid. Another advantage is that in school, you get to do lots of cool projects where you can make pepper fly or off or on a piece of paper with a balloon (or make your hair follow where ever the balloon goes if you have long hair.)
  • Static electricity is used to paint cars, the charge makes the paint spread evenly.
  • Static electricity can damage sensitive electrical components, such as the parts inside your computer. To prevent this, these parts are handled with antistatic bags and wrist straps, which drain the static charge off the person. Static electricity can also cause uncomfortable shocks to a person who becomes "charged up". To experience this shock, drag your feet across a carpet in socks, then touch your finger to a doorknob.
  • Assuming we are talking about negative effects to your computer here, the damage occurs when your RAM which is basically millions or billions of tiny electrical switches, and is found in most components of the computer (aside for just the actual RAM boards), is exposed to static electricity. The static electricity can magnetize those tiny switches and cause them to not be able to flip on and off anymore. As a result, your computer can suffer drastically reduced performance or even cease to function entirely.
  • Have you built a Vandegraff generator? Or a Leyden jar? Those things are fun!
  • Static electricity can be responsible for the ignition of flammable gases, such as the vapors produced by petrol (gasoline) when you are filling your car.
  • Static electricity can be harmful when you get a shock or by walking across the carpet and then touching a doorknob and getting a shock. But forget those dumb thing but have forgotten about those really cool experiments that we did in grades 4-8? For example making cereal fly and making pepper fly.
  • It has limited distance.
  • Well, what are we using it for? Making my hair stand up? It works for that. Or making dust stick to my monitor screen. Or causing loud crackling noises on the radio, maybe. These valuable tasks aside, static is more a nuisance than anything. If you come up with something more useful to do with static than zap my cat when I try to pet it, please let me know.
  • Static electricity develops in some circumstances in electrical insulators -- glass, plastic, etc. It's often a nuisance byproduct which can't be directly avoided in the course of doing something useful, such as making your CRT monitor operate. Sure it attracts dust, but an occasional wipe with a damp cloth isn't to high a price for most of us to pay for the advantage. If the nuisance or danger is sufficient, then some means of dissipating the static charges safely must be provided, such as the grounding straps which hang down from the gasoline tanker, eliminating the static charges before they cause a problem. I guess it's valid to ask whether we truly "use" static electricity. If you have one of those plastic oil change reminders which clings to your windshield without adhesive, you are "using" static electricity. No particular disadvantage there, with plenty of advantage over adhesive. There may be a few other cases where the presence of static charges may be anticipated and exploited, but it's generally not reliable enough to truly use.
  • Another [other than copy machines] advantageous USE of static electricity is in "painting" metallic products by a method called "POWDER COATING." As the name implies, liquid paint is not used, but the "paint" is applied to the article in the form of a dry powder.

Then the object is placed in an OVEN to soften and fuse the powder into a homogeneous film. Some objects which are painted by this method include: bicycle, tricycle, and motorcycle frames, metal filing cabinets, metal frames of office chairs and tables, etc., etc.

A dry powder sprayed on these metals DOES NOT WANT TO STICK. So, to make it stick until it can be melted/fused in the oven, STATIC ELECTRICITY IS USED. The metal object is hung on a metal conveyor line, which is charged negatively [I think], while the spray gun and paint powder is charged positively [I think. The polarity could be the other way around]. Then when the positively charged powder is sprayed onto the negatively charged object, it "sticks." Once the powder is melted/fused, it is firmly "stuck" to the metal object. Again, this is another EXAMPLE of an advantage of STATIC ELECTRICITY

  • it is used in printers to distribute the ink.
  • it is used in air fresheners and to clean up pollution.
