WHAT IS RESISTOR ? FULL DETAILS 

RESISTOR DEFINATION:-

Resistor is used for opposing current flow means use as abstacle in current flow path for low voltage and safe the electronic equipment from damage.ohm is the unit of resistor ,there are different type of resistor avalaible for the variation of voltage for protection of electronic device.the FIX resistor was discovered by OTIS FRANK BOYKIN but the resistor was DEVELOP BY GEORG SIMON OHM now which unit use as ohm for calculation,The OHM was born on march 16,1789 in the city of ERLANGEN in  BAVARIA which is NOW GERMANY. the resistor is shown on diagram as zig zag line due to the variation of resistor on current flow path.

 Resistor varies the current value when it is use in your device and provide protection from high voltage damage to your device.Different type of resistor or different value resistor available now on market like colour coding,resistance capacity which is mention by ohm value.

Every electronic asset must have resistor like your CFL bulb,TV,LAPTOP,COMPUTER,PHONE,every thing you watch of your electronic gadget must have resistor more than one with different value and colour coding.

Now small or micro SMD resistor available on market which is shape as Rectangle silver and black jacket with value mention on it
