Resistors  


                        Resistors are one of the basic component in the field of electronics. Resistors plays a major role in each and every electronic circuits. So lets see a simple thing about it.




What is resistors ????



                                    Resistors is a passive components used in all electronics circuits. It limits the flow of current through a circuit. The components which resist the flow of current in a circuit is called resistor. It's unit is ohm.

        If you ask me, a circuit will not live without resistor. Resistors plays a major role in every electronic circuits.


How it limits the flow of current??

                    

            Resistors limit the flow of current by emitting the excess of current in the form of heat.
           According to the value of the resistor, it can handle high voltages.



Types of Resistors :



1. Wirewound resistor

2.SMT resistors

3. Carbon composition Resistor

4. Thermistor.

5. Metal Film Resistor.

6.Carbon film Resistor

7. Variable Resistor

9. Varistor

10. Light Dependent Resistor


                    But nowadays in every modern electronics from mobile and laptop to satellite and aeroplane SMT resistors plays a major role than the wirewound resistors because it is small in size and it also reduces the size of all electronics and make the electronic gadgets more compatible with the users. The SMT resistors not only reduces the size but also decreasing the cost of manufacturing the resistors. The SMT resistors are cheaper when compared to the wirewound one. 

Usage: 

                    
                    Wirewound resistors are easy to mount into the PCB but it is hard and need additional skill to handle with SMT resistors.
