A length of aluminium wire is connected to a precision 10.00 V power supply, and at 20.0C the current through it is measured precisely to be 0.4212 A. The wire is then placed in a new environment of unknown temperature, and a current of 0.3818 A is measured. What is the unknown temperature? Use 0.00429 (C)^-1 for the temperature coefficient of resistivity for aluminium.
