Problem 52GP
The heating element of a simple heater consists of a 2.0-mlong, 0.60-mm-diameter nichrome wire. When plugged into a 120 V outlet, the heater draws 8.0 A of current when hot.
a. What is the wire’s resistance when it is hot?
b. Use your answer to part a to calculate the resistivity of nichrome in this situation. Why is it not the same as the value of ρ given for nichrome in Table 22.1?
