Electricity is almost as common as running water in many areas, especially in the face
Developed countries. Despite this,
there is great ignorance about this strange power, and how
about. Well, I can prove that it is atoms and electrons, protons, 's
and neutrons they contain.
If you imagine an atom as a spherical image, the core at the center
that at least one proton and at least one neutron. The protonis
positive charge. In orbit around the nucleus of at least one electron
is negatively charged. The reason we have these opposite charges takes us deep
in quantum physics. We know that the neutron is composed of quarks and
Electron is an elementary particle (is not everything, and it is a
The particles themselves), but why are opposite charges is a

elements separated from each other. Although described as a sub-atomic particles
The electrons have the properties of both particles and waves. In theory
at least they could have both at the same time.
If an atom has no electric charge, that is neutral, then it contains
the same number of protons and electrons. In some materials – most of the metalsfor
Example – the electrons orbit the nucleus is very loose and may be adopted by the spin of the atom. When this happens, the atom
is positively charged protons, because in most within the atom.
A free electron can be joined to another atom. If this happens then its new host atom is negatively charged because the electrons

The most important thing to remember is that opposites attract. L 'the greater the
Difference between the number of electrons and protons, the higher the

Often, an electrical device requiresvoltage other than that

Take, for example, confidence ratings Insectocutor killing machine with an electrified grid.
This will generally require 4000 volts to operate. These machines
