lesson 1

• Electronics

  The study of the behavior of an electron and the different conditions of applied electric field
• Electronic device

  A device which controls the flow of electrons
• Electronic devices are the main building blocks of electronic circuits
• The motion of electrons through a conductor gives us electric current
• This electric current can be produced with the help of batteries and generators
• Branches of electronics

  • Digital electronics
  • Analog electronics
  • Micro electronics
  • Nano electronics
  • Opto electronics
  • Integrated circuit
  • Semiconductor device
• Diode vacuum tube was the first electronic component invented by J.A. Fleming
• Lee De Forest developed the triode, a three element vacuum tube capable of voltage amplification
• Bell Laboratories developed the first transistor based on the research of Shockley, Bardeen, and Brattain


  1947
