Basic Electronics Presentation

  1. 1. Preparedby:FAZLIKHALIQ
  2. 2. Preparedby:FAZLIKHALIQ
  3. 3. ELECTRONICS  The branch of science/physics which deals with the study of electricity and electrical devices is called Electronics.  The branch of science/physics which deals with the transistors ,capacitors , conductors and insulators etc.  In which we study about the controlling of electric currents. (i.e to stop, to flow, to maximize or to minimize a current).  In which we deals about the electric circuits.  In which we study about the flow of electrons. Preparedby:FAZLIKHALIQ
  4. 4. ELECTRONICS  The electronics deals with the Diodes, PN Junction, Rectifier, Bridge Rectifier, accumulator and AC and DC circuits.  The field of electronics was invented in 1883. Preparedby:FAZLIKHALIQ
  5. 5. ELECTRICITY  Electricity is the flow of electrons in a specific media is known as Electricity.  The electricity flows through atoms . Atoms is every material which is made up of electrons, proton and neutron.  The electron and proton hold the atoms together. i.e positive and negative charge hold the atom. Preparedby:FAZLIKHALIQ
  7. 7. CONDUCTORS  The device/material used for moving/flowing of electrons is known as conductor.  In conductors the electron freely move from one atom to another.  We can also call that those device/material in which electricity /electric current pass through it is called conductor.  EXAMPLES:  Copper, silver, gold etc. Preparedby:FAZLIKHALIQ
  9. 9. SEMI-CONDUCTOR  A device/material which having dual functionality is called semi-conductor.  A semi conductor is a device which having quality of both conductors and insulators.  A semi-conductor can conduct/pass less than conductor and more than that of insulators.  A semi-conductor devices are basically used for transiting /resistance. Preparedby:FAZLIKHALIQ
  10. 10. SEMI-CONDUCTOR  The semi-conductor have four electrons in outer orbit. Two electrons used for less conducting and two are used for insulating.  EXAMPLES:  Carbon (C ): Carbon is a good semi-conductor.  Germanium (G): Germanium is also semi- conductor.  Silicon (Si): Physically all transistor are made of silicon and silicon is a semi conductor. Preparedby:FAZLIKHALIQ
  11. 11. TYPES OF SEMI-CONDUCTOR  There are two types of semi-conductors:  1)INTRINSIC Semi-conductor:  A semi-conductor used for conducting/flowing of electricity, heat and sounds is known as intrinsic semi-conductor.  2)EXTRENSIC Semi-conductor:  A semi-conductor device used for insulating/resisting of electricity, Heat and sound is known as extrinsic semi- conductor. Preparedby:FAZLIKHALIQ
  13. 13. INSULATOR  A device/material which can not allow free movement of electrons is called Insulators.  The electric current/electricity can not pass through it.  In insulators there are electrons but only stay in orbits and can not move freely.  An insulators can hold or store electricity but can not conduct/pass electric current /electricity. Preparedby:FAZLIKHALIQ
  14. 14. INSULATOR  Insulator is used for stopping/prevent of electric current/electricity.  Capacitor is an insulator.  Capacitor: Capacitor is a device which store electric charge and good insulators. Capacitor is used for breakdown of current and voltage.  EXAMPLES:  Rubber, Glass ,Plastic, Paper and Air etc. Preparedby:FAZLIKHALIQ
