The birth of electricity comes from what we call an atom or atoms and its interaction with other atoms. The contents of an atom are in three parts, a proton, a neutron, and an electron. The proton is known to be with a positive electrical charge. The neutron is known to be neutral or without an electrical charge. The third particle is called an electron which is known to be with a negative charge. The center of the atom (nucleus) would contain both the proton, and the neutron. The electrons have a negative charge. The Protons have a positive charge. The neutron has no charge, or is neutral. Like heat is attracted to cold, negatively charged electrons are attracted to the positively charged proton. The positively charged proton, and the neutron which has no charge, are found to be stationary in the center of the atom, called the nucleus. Many negatively charged electrons can revolve randomly around the proton and neutron, at the same time, and in different orbits. The negatively charged electron (energy) would be attracted to the positively charged proton due to the attraction created by the opposite forces.

        Some types of structures are called non-conductive (some plastics and ceramics), and some are called conductive (metals). An atom with the least amount of free electrons in its outer orbit are called insulators (non-conductive) An atom with many free electrons in its outer orbit are more conductive(conductors). Non-conductive characteristics are the molecular makeup of insulators. Conductive characteristics are the molecular makeup of conductors containing many free electrons in its outer orbit. An example of an atom that allows many free electrons and readily looses or gains it total number of free electrons makes it a good conductor of electrons and would have a conductive property similar to copper. Copper is a very good conductor.

           The passing and accepting of a free electron creating electricity can be done in several different manners; Chemical energy(battery), Solar energy (Power collected from the sun in solar batteries or collectors, friction force (Generators).                 

         

 

         Now a proton, or neutron will remain stationary, within its own nucleus, but an electron is continually moving (revolving around the nucleus) If, the electron in an atom’s outer orbit is made to move fast enough around its nucleus, this electron may break free from the outer orbit of that atom and transfer to a different atom.

        The movement of electrons is called current.. The force created in the movement of electricity (an electron breaking free of one atom and moving to a second atom) {not the movement of that electron as much as the action of breaking free from the outer orbit of that host atom thus increasing the charge of that electron) is called  (voltage).

The most important relationship in electrical science is  that between the applied e.m.f or p.d and the current established by it. This relationship is known as Ohm’s law and it was discovered by Georg ohm in 1826. George ohm who was the first scientist to develop the idea of resistance, carried out experiments with different metal wires to discover how the current through each depended on the p.d. applied across its ends. If a test is conducted, in which a circuit is setup with an ammeter and a voltmeter and if a metal is add to the circuit then a ...
