While taking photographs in Death Valley on a day when the temperature is 51.0°C, Bill Hiker finds that a certain voltage applied to a copper wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is -88.0°C? Assume that no change occurs in the wire's shape and size. At the low temperature T we write R = R0 [1 + a(Tc — To)] where To =? tW AV At the high temperature Th, Rh = = R [1 + a(Th — To)] My question is how do i find what To is?
