A lab 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 60.0°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 X 10-3 (°C)¯1. (Assume that the reference temperature is 20°C.)
