Temperature effect of resistance in conductor

THERMAL EXPANSION OF RESISTANCE IN CONDUCTOR   
  • Thermal expansion of Resistance in Conductor:-
  •  Thermal expansion of resistance in conductor present in "Linear Expansion".
  • Linear Expansion of Resistance:-  
  • Any Conductor change of resistance is directly proportional to the original resistance as well as change of resistance is directly proportional to the temperature difference.

                      
 
  • If Resistance at zero degree Celsius is Ro ,Find The Resistance at T degree is Rt:-  
                           
                        
  • If Resistance at T degree Celsius is Rt ,Find The Resistance at zero degree is Ro:-
                            
                  


                 
  • If Resistance at zero degree Celsius is Ro Find the Resistance at T degree Celsius is Rt But thermal coefficient given at zero degree Celsius:-
