What is the change in the wires resistance

Reference no: EM13703546

Solve the all parts of given question:

Question: A copper wire has a 25-m ohm resistance at 20 C. When the wire is carrying a current, heat produced by the current causes the temperature of the wire to increase by 27 C.

Part I: What is the change in the wire's resistance?

Part II: If its original current was 10.0 mA, what is its final current?

I need the right answer and steps of solving these questions. Thanks!
