STATIC ELECTRICITY BY: AHMED AL MISNAD 8E

WHAT IS STATIC ELECTRICITY Static electricity is an excess of electrical charge on a surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electrical current or electrical discharge. Static electricity is generated when any material gains or losses electrons and becomes positively (when it loses electrons) or negatively charged (when it gains electrons ). The accumulated charges are what called static electricity.

USES OF STATIC ELECTRICITY Dust removal: there are some appliances that can eliminate dust from the air, like air purifiers. They use static electricity to alter the charges in the dust particles so that they stick to a plate or filter of the purifier that has an opposite charge as that of the dust (opposite charges attract each other). Photocopy: Copy machines use static to make ink get attracted to the areas where we need the information copied. It uses the charges to apply the ink only in the areas where the paper to be copied is darker (usually this means text or other information) and not where the paper is white, this process is called xerography. Car painting: To make sure a car's paint is uniform and that it will resist the high speeds and weather to protect the car's metal interior, it is applied with a static charge. The metal body of the car is submerged in a substance that charges it positively, and the paint is charged negatively with the paint sprayer.

EXAMPLES OF STATIC ELECTRICITY Static electricity is produced when two objects are rubbed together. Examples of static electricity are as follows. rubbing a balloon on your head, and bringing it close to a wall and seeing if it stays mounted. shuffling your feet across a carpeted floor and then touching a metal object.

PROBLEMS OF STATIC ELECTRICITY (MAN- MADE) New science reveals, not radiation, but static electricity produced by power lines interferes with the bioelectrical life process causing illnesses cancer and premature aging. New science about the real danger of power lines, which is not EMF- radiation, but static electricity that interferes with the nervous system and the bio-chemical life process of the human organism causing diseases.
