Transistor is a three terminal electronic component that is used to amplify the electric signal as well as used as a switch. Real view of transistors: Symbol of transistor:  E = emitter                                                       B= base                                                              C= collector                                  Terminal identification of transistor:                                                                 It depends on value and type of transistor. NOTE: It's also made of semiconductor materials. There are many type of transistor . It's use as a switch. It's use as a amplifier.

   Diode is a two terminal electronic component that is used to flow of current in only one direction.

A Resistor is an electronic component that limits/resists/regulates the flow of electric current  in electronic circuit. resistors can also be used to provide a specific voltage  for an active device such as a transistor .                                                   Real view of resistor:                                Symbol of resistor:            NOTE: It has no polarities. There are different kinds of resistors .  It emits energy in the form of heat.

You will be familiar with the new development in Electronics .you can experience the importance of electronics from this point of view that different device around you are based on electronics. AS.... Television, Radio,Laptop, Mobile phone, Telephone , VCR, CD player, Tap Recorder and all devices based on Electronics has Revolution our lives. Electronic gadgets WHAT IS ELECTRONICS :                                                                                                                                           " E lectronics is that field of science and Engineering in which we study the device based on flow of   Electrons and their applications. Electronic device are those in which current flows due to motion of electrons in semi-conductors." Literally means electronics 👇                      ELECTRONICS= ELECTRON+DYNAMICS Applications of electronics in different field : Electronics has significant contribution in different areas......
