Question:

(a) What is the percentage variation of the resistivity of copper over the temperature range from room temperature (20oC) to 100oC?
(b) Assume that a copper wire’s resistance changes due to only resistivity changes over this temperature range. Further assume that it is connected to the same power supply. By what percentage would its current change? Would it be an increase or decrease?
