Electrostatic discharge 05/16/16
Have you ever wondered why you get shocked sometimes when you reach for a doorknob? This is due to the effects of electrostatic discharge. Electrostatic discharge is the sudden flow of electricity when two charged objects become contiguous with one another. Often times, an electric spark is created during the occurrence of the phenomena. Electrostatic discharge can have a very harmfull effect on hardware, so extra protection is often necessary to keep everything safe.

questions about protons has plus charged
it has two up qwarks and a down and it be a positive. but we can relate charges on the particle to the its mass? then positively charged proton has more mass than negatively charged election. so we can say that proton has more up quarks so it has more mass. but in case of neutron it has less up quarks than proton. so why it has more mass than poton?

Hi Chaudhary, thank you for asking. This is because electrons have been empirically demonstrated to have less mass. Read more about it here. https://physics.stackexchange.com/questions/331699/why-are-protons-heavier-than-electrons
