10. -11 points SerPSE 10 26.4.OP.011. My Notes Ask Your Teacher A physics 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 53.0°C and notes that 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 x...
