A length of aluminum wire is connected to a precision 10.00-V power supply, and a current of 0.4212 A is precisely measured at 27.0 ∘C. The wire is placed in a new environment of unknown temperature where the measured current is 0.3804 A . --------------------------------------------------------------------------------------------------------------------------------------------------- For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 4.00 −kΩ−kΩ resistor from a carbon resistor and a Nichrome wire-wound resistor connected...
