Page1 Engineering 120 Introduction to Electricity Electricity is the ow of electric charge For us this amount to the movement of electrons or protons A proton is positively charged and is composed of two up quarks and a down quark An electron is negatively charged and it is believed to be a fundamental particle There are three types of materials that electricity can possibly move through A conductor is one in which electricity can easily ow through A semiconductor is one in which electricity can ow through under certain conditions An insulator is a poor conductor thus electricity cannot ow it Some examples of the three would include Conductors Semiconductors Insulators Copper Integrated Circuits Glass Gold Transistors Plastic Aluminum LEDs Rubber Some materials conduct better than others due to the atomic structure This is de ned as the ability of a material to conduct electricity depending on the arrangement of electrons around the nucleus For example Copper Cu has an atomic number of 29 and an atomic weight of 63546 gramsmol The atomic number indicates the number of protons in the atom So if we subtract the total amount of protons from the atomic weight which rounds to 64 we are left with 35 neutrons In short the number of protons added to the estimated number of neutrons will result in the same number as the atomic weight Now valence electrons in the outer shell in uence conductivity The Bohr Model predicts that electrons will con gure themselves into shells around the nucleus of an atom EH 13 ESEEFE E i gp a fl 431 It is easy for Copper to let go of the valence electron whereas in an insulator the outer electron shell would be full This way the insulator would hold on tightly to its valence electrons thus causing the need for a higher voltage to induce electron ow Page2 Electric Current The net ow of electrons through a material is called a current When the ow is from positive to negative it is known as a conventional current The conventional current is known as when we measure or computer currents Due to atom oscillations the path an electron may take is very scattered Electric Resistance Consider the interaction of electrons with ions as they pass through a material quotatoms oscillate about their equilibrium positions due to thermal energy the amplitude of oscillation increases with temperature the conduction of electrons through a material is interrupted due to destructive interactions with oscillating atoms this scattering and destructive interaction cause electrical resistance as well as heat generationquot In short this means that if it has a temperature there are oscillations These oscillations cause friction and decrease conductivity due to the rising temperature The decreased conductivity causes resistance Electrical resistance is therefore the measure of the opposition of materials to the passage of electric current Resistance is annotated as R kaage electn n s homage l The potential difference between the strength of the electron shortage and the electron supply de nes the voltage Voltage is a measure of how badly electrons want to cover a distance It is electrical pressure energy that will be spent Voltage is measured as EMF electromotive force Page1 Engineering 120 Introduction to Electricity Electricity is the ow of electric charge For us this amount to the movement of electrons or
