Static electricity GapFill

A build-up of charge is known as  no currentstaticpositivenegative electricity. Charge can only build up on  magneticinsulatingconductingnuclear materials because the charge cannot dissipate.
When two objects rub against each other,  neutronselectronsionsprotons are transferred from one material to the other, causing the two objects to become oppositely charged, so they  repelfeel no forceattractstore energy. When charge builds up like this, there is a potential difference between the oppositely charged objects. If the potential difference increases enough, there is  a sparkstatica bolta shock as charges jump across the gap. This can be very dangerous as it can ignite flammable materials or gases, so, in factories or petrol stations, objects need to be  groundedchargedzeroedheated to stop this from happening. One useful application of static electricity is in pesticide sprays; the aerosol droplets are all given the same electrostatic charge as they leave the spray nozzle, meaning that they  fly outwardsattract each otherrepel each otherare sprayed and spread out covering a wide area. Their charge also means they are  sucked towardsfamiliar topulled towardsattracted to the neutral plant material that is being sprayed.
