The heater element of a toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. The resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 Ω·m. Assume the toaster is operated at a constant voltage of 120 V. -When the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to its resistivity when at operating temperature? Explain.
