Chapter 22, Problem 53(choose chapter or problem)
The heating element of a simple heater consists of a 2.0-mlong,0.60-mm-diameter nichrome wire. When plugged into a120 Y 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 ofnichrome in this situation. Why is it not the same as thevalue of p given for nichrome in Table 22.1 ?
