Static GapFill

A build-up of charge is known as  negativepositivesparkinginsulationstaticno current electricity. Charge can only build up on  conductingcoldinsulatingchargedmagneticnuclear materials because the charge cannot dissipate.
When two objects rub against each other,  ionsneutronsprotonsnucleiatomselectrons are transferred from one material to the other, causing the two objects to become oppositely charged, so they  charge upfeel no forcedissipate energystore energyrepelattract. 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 cracklethundera shocka sparka boltstatic 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  chargedheatedzeroedgroundedlivecooled to stop this from happening.
