Calculating the Resistance of an Aluminium Wire at a certain Temp. 

Aluminum wire of temperature coefficient 0.006c is heated to a temperature of 60c. Due to temperature changes, it is required to calculate its resistances when it is at zero and 60c respectively.
Hence, we calculate using these relations: R1 = Ro(1+¶∆1)
R2 Ro(1+¶∆2)
Learning this concept is crucial for estimating the variation of resistance with respect to temperature increase.
