What is electricity?

Rubbing together of two bodies , such as compression or during any mechanical effects that occur due to the influence of heat and impact that some of the crystals , pulling, pushing , mechanical, chemical or thermal events, showing the form of an energy çeşitielektrik
        People amber power centuries ago , for example , the friction of the fabric after the event to attract dust and hair with light as he recognized the bodies . This is the first experiment the Greek philosopher and scholar, Thales ( 640-546 BC ), this event is not only thought about kehribarla and electron (Greek amber ) used the name . Several years after the law was electricity .
        Friction caused by static (stationary ) Italian scholar A. The presence of electricity other than electricity flowing Volta begins his experiments . This information is obtained from the first electric battery and the electric current to the first başarabildi.Çok that although there are ancient history even in the 1890s, physicists, " What is electricity ?" sormaktaydılar question them . Several theories seek to answer this question , it was finally answered after the coining of the modern atomic theory .
         According to Rutherford's atomic model of Bohr and positively charged protons and uncharged neutrons in each atom from the negative electrically charged electrons orbiting a nucleus , and it is composed . Neutral atoms in the normal state , ie, no load. Because the number of electrons is equal to the number of protons . Electric current is the data available today can be explained as follows : the outer shells of the atoms in the group substances called conductors , electrons from an atom of a neighboring atom at random and move freely . These electrons are called free electrons .
         Extremely large number of free electrons in semiconductors . Random movements is not exposed to any external effect as long as the number of electrons moving in a direction considered equal to the number of those who can move in the opposite direction . Thus , there will be moving in a certain direction . Whereas one end of an outer conductor of a lead to a surplus of electrons and electron deficiency occurs at the other end , two free electrons in the conductor are exposed to an electrostatic force . These positive terminal ( electron deficient end) towards pulling force and the negative terminal ( the terminal electron excess ) beyond the right of the pushing force . In this case, random movement of free electrons to the positive terminal while at the same time continue the movement or flow of electrons observed clearly . This flow of electrons is called an electric current . A size of an electric current , flowing through a conductor per unit time, the negative electric charge ( electrons ) is defined as the amount .
        Both ends of the above-described event conductor , the ends of the potential difference or voltage can be obtained by connecting the ends of a battery or generator . Amps unit of electric current intensity . 1 ampere per second, equivalent to about 1018 electron flow quantity.
