why static electric is very related to relative humidity?

Like capacitors, the voltage rating is where the voltage will break down the medium and conduct. Air is exactly the same. One can only build up charge (static electricity) until the voltage is high enough to cross the barrier, like an air gap. Humidity is water in the air. (Actually, the total amount of water(absolute humidity)and not the relative amount, is the important number.) (Say a cold day with 100% humidity is more of a problem than 30% on a hot day). The water more easily contributes free electrons, the voltage accelerates the charge which in turn ionizes more air, conducts more electricity to ground or someplace. The wrist ban, straps conduct electricity to ground, or at least leaves you and the electronics at the same potential.

When it is cold and dry outside, the friction of your car going through the air creates static on your car. When you get out, you provide the shortest path to ground and the static electricity goes through you. If you hold onto the metal on your door while you are getting out, you will not be shocked.

Static pressure is usually associated with the pressure inside a vessel or duct. When your air conditioning at home kicks on, the blower builds up static pressure in the ductwork. The registers blow out air because of this static pressure relief through them.

I assume you are talking about a static shock.\n\nTo put it simply. The body is a pretty decent conductor of electricty as well as a capacitor (something that stores electrical charge). When electric charge builds up, but has no place to go thats what we call a static charge. You can see this when you rub a balloon on your head and it makes your hair stick up, and the balloon may even stick to your head. This is due to static electricity.\n\nWhen you have a charge built up on your skin, but have not grounded yourself, say by touching something metal, that charge will remain there until it has someplace to go. Electricity will move in the direction of least resistance, and as soon as you touch another person, or a ground of some sort it "jumps" from its stored state (static state) into the least (or less) resistive medium.

think so... we all have static electricity in our body...

It is called static electric.

Static electricity is a class of phenomena involving objects with a net charge; typically referring to charged objects with voltages of sufficient magnitude to produce visible attraction, repulsion, and electrical sparks.\n\nStatic electricity can be a serious nuisance in the processing of analog recording media, because it can attract dust to sensitive materials. In the case of photography, dust accumulating on lenses and photographic plates degrades the resulting picture. Dust also permanently damages vinyl records because it can be embedded into the grooves as the stylus passes over. In both cases, several approaches exist to combat such dust deposition. Some brushes, particularly those with carbon fiber bristles, are advertised as possessing anti-static properties. Also available are handheld static guns which shoot streams of ions to discharge static on records and lenses.\n\nNote that the presence of electric current does not detract from the electrostatic forces nor from the sparking, from the corona discharge, or other phenomena. Both phenomena can exist simultaneously in the same system.\n\nStatic electricity is an important element in the biological process of pollination by bees, since the charge on a bee's body helps to attract and hold pollen.

Static electricity.  Just connect yourself to a ground and you'll be OK.

A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain -- it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.\n\nHumans are very sensitive to humidity, as the skin relies on the air to get rid of moisture. The process of sweating is your body's attempt to keep cool and maintain its current temperature. If the air is at 100-percent relative humidity, sweat will not evaporate into the air. As a result, we feel much hotter than the actual temperature when the relative humidity is high. If the relative humidity is low, we can feel much cooler than the actual temperature because our sweat evaporates easily, cooling us off.

Because winter has the driest air of any season.\nThere is generally less general moisture in the air.  On top of that, people usually have the heat on in the home, which dries the air out even more.\n\nWant to cut down the static electricity?  Buy and use a humidifier.

That is a fantastic question.\nIt is a matter of humidity. The cold weather\nthat allows snow means the air is not humid\nenough to allow an electric current to travel\n(along the water vapor in the air) over the differently\ncharged clouds and sky. People who say temp are\nsort of right, but it is the low temp that leads to the low\nhumidity that causes the "problem".\n\nThanks for asking such a good question.

Dry air plus synthetics equals static. There really isn't a cure. Try to wear cottons or use an anti-static such as static guard. They'll help some. \n\nTo avoid shocks from touching things, try to use a pencil, key, or other object to touch things first. It will drain off some of the charge and if there is a discharge, it won't be directly on your skin. If you are wearing rubber soled shoes, such as running shoes, don't scuff them on the carpet. This raises a ton of static.

Absolute humidity is the amount of water in a given volume of air.\n\nRelative humidity is the amount of water in a given volume of air relative to the maximum amount that could be there without condensation occurring.

It has to do with negative and positive ions.  Before an approaching thunderstorm the atmosphere is positively charged.  These positive ions can cause such things as headaches, body aches and a general ill feeling. \n\nThunderstorms, lightning or static electricity to be exact, are full of negative ions which rid the atmosphere of the positive ions.  They also clean the air of positively charged particles.  Air cleaners work the same way.  They put out negative ions that attach themselves to positively charged, dust, pollen and other particles, removing them from the air making it fresher and cleaner.  \n\nThat is why we feel better after a nice thunderstorm because the air is fresher, cleaner and has less allergens and pollutants. \n\n I love thunderstorms.  Nature's air cleaners.

A lot of static electricity in the air can cause "dry lightning".  I assume that is what happened.

It seems like you could figure the relative humidity based on the pressure, temperature, specific volume, etc.  After that you could figure the volume of condensation on a per cubic meter basis.  You would need a total volume to come up with the total mm/day.  Hope that helps get you going on the right path to an answer.  If not, you should re-post your question with additional information- I get the feeling you left something out.

Relative humidity is a term used to describe the quantity of water vapor that exists in a gaseous mixture of air and water.\n\nDefinition\nRelative humidity is defined as the ratio of the partial pressure of water vapor in a gaseous mixture of air and water to the saturated vapor pressure of water at a given temperature. Relative humidity is expressed as a percentage and is calculated in the following manner:\n\nRH = {p_{(H_2O)} &#92;over p^*_{(H_2O)}} &#92;times 100%\n\nWhere symbols in the above equation have the following meaning:\n\n{p_{(H_2O)}} is the partial pressure of water vapor in the gas mixture;\n\n{p^*_{(H_2O)}} is the saturated vapor pressure of water at the temperature of the gas mixture; and\n\nRH_{&#92;,_&#92;,} is the relative humidity of the gas mixture being considered. \n\nYou could get more information from the link below...
