Alab technician is studying the effect of temperature on the resistance of a current carrying wire. she applies a voltage to a silver wire at a temperature of 57.0°c and notes that it produces a current of 1.50 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 silver is 3.80 ✕ 10−3 (°c)−1. (assume that the reference temperature is 20°c.)
