Aphysics student is studying the effect of temperature on the resistance of a current carrying wire. she applies a voltage to a iron wire at a temperature of 59.0°c and notes that it produces a current of 1.40 a. if she then applies the same voltage to the same wire at −88.0°c, what current should she expect (in a)? the temperature coefficient of resistivity for iron is 5.00 ✕ 10−3 (°c)−1. (assume that the reference temperature is 20°c.)
