Given information
It is given that the length of aluminium wire is connected to a precision 10.00-V power supply, which gives a current of 0.4212 A at and 0.3818 A at an unknown temperature. It is also known that the temperature coefficient of resistance of aluminium is
Step-by-step explanation
Step 1.
The resistance R at temperature is correlated to the reference temperature and the resistance at that temperature is as,
Varying resistance with temperature is
Here, is the temperature coefficient of resistance of the given material
