What causes static charges?

Answers

When internal workings of a computer are exposed, it is possible to damage the computer with
static electricity held by the human body.

Whenever the casing of a computer is opened and its internal workings are exposed to change
a hard drive or add memory chips for example there is a danger of damaging the computer with
the buildup of static electricity that is held by the human body.

Static electricity is caused by a process called triboelectrification (process by which two
originally uncharged bodies become charged when brought into contact and then separated.).
Everything around us, and including us, is made of atoms, and every atom has in its center
(nucleus) positively charged protons and neutrons, which have no electrical charge. Surrounding
the atom are negatively charged electrons. The protons and neutrons in an atom do not change,
but the electrons can move from one atom to another. When two objects touch, they exchange
electrons, which causes one object to become electrically positive and the other to become
electrically negative. When an object touches another object with either an opposite or neutral
charge, electrons flow. Static electricity is created when electrons move back and forth between
atoms.
