How does ideal gas differ from real gas?

Topic: Electrostatic Induction


July 24, 2015

What is an ideal gas how does it differ from the real gas and why is it necessary to study the ideal gas equation and its properties

sidanga - South Africa



An ideal gas is a simplified version of a real or actual gas. It considers the atoms or molecules as small, hard spheres. Also, collision are elastic and all motion is frictionless.

This provides a good approximation of the behavior of a real gas, except that at lower temperatures and higher pressures, many ideal gas equations do not hold.

What causes lightining to spark?

Topic: Static Electricity and Lightning


July 15, 2015

What courses lightining to spark?

Holder - Lesotho



Lightning is caused by a large number of electrons jumping from a cloud to another cloud or some object on the ground. It is like an explosion of electrons. When the electron rush through the air, they excite the air molecules and heat up the air in their path. The air gets so hot that it glows and gives off light. It also expands due to the heat.

But this happens only for a very short time. Once the electrons stop flowing, the air suddenly cools off and collapses, causing the noise of thunder.

How do you permanently ground a conductor?

Topic: Electrostatic Induction


June 9, 2015

Greetings. But how do you permanently ground a conductor?

Kevin - Botswana



In AC and DC circuits, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.

However, in electrostatics, you want to draw off excess charges to a large object. It can be the Earth or much smaller objects. Note that in electrostatics, permanently ground could draw off all charges.

What causes sparks when removing clothes?

Topic: Static Cling


May 6, 2015

What cause spark when removing clothes from your body?

Solomon - Uganda



When clothes rub against your body static electricity can build up on the cloth. This is especially true for polyester cloths and when the skin is dry. If there is enough static buildup, it can cause a spark to fly between the clothes and the skin. This usually happens more when the air is dry than when it is humid outside.

Always getting shocks

Topic: Reducing Static Electricity Shocks


April 25, 2015

i have big problem now with my Body..if i touch any object even to people i got a electric shock ..rightnow,i am afraid to touch anything coz there is sparks or electric when to touch. Please help me? Why i got this ??when i was in the philippines i didnt encountered this kind of illness.

Gracel - Qatar



Static electric shocks can happen more when the air is dry, as it usually is in Qatar. However, in the Philippines, the air is more humid, which stops the shocks.

One thing that could be causing your problem is dry skin rubbing against your clothes. If you can, try some moisturizing lotion on your skin. Also, polyester clothing causes more shocks than cotton. See if wearing all cotton clothes helps.

You can use a metal key to touch metal objects such as doorknobs to drain off the electricity in your body.

Hopefully, these ideas will help. Best wishes on stopping the static shocks.

Static precautions in repairing a laptop

Topic: Static Electric Materials


April 9, 2015

Stumbled on your "Effect of Materials on Static Electricity" article today. Appreciate it.

I need to attempt a repair on one of my older laptop computers and want to prevent ESD damage. I have ordered an anti-static wrist strap which I will alligator-clip/ground to the center screw of an electrical outlet, but I am also thinking about using a cotton towel (on a wood dining room table) as a work surface. I've looked into anti-static mats as well, but I don't really think any of them but the more expensive ones will effectively dissipate ESD.

So I'm thinking I may as well focus on draining ESD from my person via the wrist strap and then use a cotton towel mat to keep static electricity to a minimum of the work surface.

What do you think? about using a plywood square as a mat?


Robert - USA



I think your precautions should be sufficient, especially if you haven't experienced any static electricity around your work area. I think simply working on the wood table might be better than on a cotton towel, which can slid around and perhaps build up charges.

With the lower prices on many laptops, it often is not worth repairing an older model. Also, they are tough to repair as compared to a desktop computer where modules are easily removed.

Best wishes on getting things running again.

Where do amber and ebony fit in static electricity?

Topic: Causes of Static Electricity


March 25, 2015

where do materials amber & ebony fit into the picture if at all

Cliff - Australia



Both amber and ebony can acquire an electric charge by rubbing with a material like wool.

See Effect of Materials on Static Electricity for a relative listing of materials creating static electricity.

Friend sees sparks or light when plugging into an outlet

Topic: Reducing Static Electricity Shocks


March 24, 2015

Sorry this may not be the same as static shock but just a question maybe you can help for a friend is it possible to see lights comes out of the sockets when plugging in to sockets ???

Debbie - UK



Some devices cause a small spark when plugged into an outlet. I know that when I plug in my laptop, I always see a small spark. It doesn't seem to hurt anything.

The only time such a spark can be dangerous is if there are inflammable gases or fumes in the air nearby. The spark could then set off an explosion.

Would static set off store alarms?

Topic: Reducing Static Electricity Shocks


March 19, 2015

Hello. I have a problem when when entering or exiting certain stores I.e the alarm systems are triggered, much to my embarrassment. Could this be due to my body static which I think could be fairly high? Have you any suggestions. would really appreciate your help.
Olive Allison. (UK)

Olive - UK



I wouldn't think your static electricity would set off one of those alarms. Usually, they are set off through using a low powered radio signal that detects an RF tag that acts as an antenna. If you have such a tag in some object, the device would detect you going in or out of the store. The RF tag can be deactivated at the time of purchase.

Is it possible that you have such a tag stuck in an item of clothing, your purse, or some other object you take into the store?

If you did have high body static electricity, you would probably be annoyed by getting tiny shocks when you touched metal items. But still, I don't think that would set off the alarms.

Benedictine monk has problems with static electricity

Topic: Static Cling


March 13, 2015

I am a Benedictine monk. We wear habits which are generally made of wool or wool and an artificial material combined.

(please read the last two paragraphs before you read the rest.)

I recently got a different habit, and for the first time in the sixty-five years that I have been a monk my hood keeps sliding off my right shoulder. This happens especially when I reach for something that is waist-high or lower, which I automatically do with my dominant right hand. I suspect that the problem is a hood with a fabric that repulses a garment beneath it.

The the hood, which we put up only when outside in the cold a a light rain, is separate from the garment called a scapular beneath it (two joined full shoulder-wide strips of cloth), but they seem to be the same type of material. And under that is another garment which also seems similar. The latter two garments reach almost to the ground. Beneath them are trousers and whatever underwear one may be wearing.

Because the other habits I've had had never slipped and slid like this hood I think that this may be static electricity which repels the hood, the sides of which are supposed to lie flat gently for about three inches on the shoulder.

The front of the hood is open, and both ends of the front have button holes, which hold the the hood on to a button attached to the scapular right below it.

I have always listed a bit to the right, but my boss tells me that I'm just listing a bit more.

I did try putting a safety pin through the bottom of the hood thinking that that might of somehow neutralize the static repulsion, and the first couple of days I thought it was working just splendidly. But then I put another pin in and thought it worked worse. But I wasn't sure where I had put the pin that seemed to work so I kept trying other places, but nothing worked. So I tried two bigger ones, but that didn't help.

Now while I was writing this I realized I should try the one small pin again, and that did seem to work just fine. But it's getting to be too late, and I want to close my computer for the night, and don't know how to save this so that I could send it later. And I'm tired.
I'll write again and tell you how it is working.

Thank you for reminding to check my address, as an "h" had gotten into it by mistake.


Thomas P - USA



It is possible that your new habit includes more polyester material, which could contribute to increased static electricity and perhaps cause the slipping.

Using a metal pin could not only help hold the items together but will also help drain off some of the charges.

I hope the pin is the solution to your problem.
