: A Copper Wire Has A Resistance Of 0 435 At 20 0 C And An Iron Wire Has A Resistance Of 0 458 At The Same Temperature A 1 (20.49 KiB) Viewed 41 times

A copper wire has a resistance of 0.435 at 20.0°C, and an iron wire has a resistance of 0.458 at the same temperature. At what temperature are their resistances equal? The temperature coefficient of resistivity for copper is 3.90 x 10-³(°C) -1 and for iron it is 5.00 x 10-³(°C)-¹. °C
