An engineering intern is studying the effect of temperature on the resistance of a current carrying wire. She applies a voltage to a aluminum wire at a temperature of 57.0°C and notes that it produces a current of1.50 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 aluminum is 3.90 x 10-3 (°C)-1. (Assume that thereference temperature is 20°C.)
