Dry air, synthetic materials and carpeting are the common culprits when it comes to causing static electricity. Getting rid of static is not a step-by-step process, but there are tricks and tools to use to help reduce the static build up in your home and clothing.
In general, they employ an alpha emitting radioactive source, usually polonium-210, to ionize the air immediately in front of the device. The ions produced in the air (positively charged oxygen and nitrogen molecules, and negatively charged electrons) are then attracted to the object that has the static charge.
Specific effects may include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are made with an ion generator, sometimes called an ionizer, in the same unit. You can also buy ionizers as separate units.
If your electronics is grounded, charges should not build up on the circuitry itself. If the air is ionised enough any charges built up on plastic parts will leak away to the grounded circuitry.
The fastest way to get rid of static electricity in the body is to let the electricity do what it wants – discharge from your body into the ground. To allow this, touch any conductive material not isolated from the ground such as the screw on a light switch's panel or a metal streetlight pole.
You can ground yourself by touching anything that is metal. This will make the current in you go into the metal because the metal is a better conductor of electricity than you are and it goes in the path of least resistance. A convenient source of metal is the computer case, the metal parts of the housing.
Yes. The static electricity is discharged to ground via the case, the PSU earth wire, house/building earth wire, and then to earth/ground via an earth rod or earth mat.
Use a non contact voltage detector. With the carriage in the home position, open the access doors and enable the non contact voltage detector just below the anti static bar on either side. Gently move back and forth and up and down. When voltage is detected an audible beep will be emitted.
Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits energy.
Static electricity is caused by your body picking up free electrons as you walk on the rugs. When you have extra electrons on your body and you touch a metal conductor, such as a door handle, the electrons flow into the object and you get a static shock.
