A copper wire has a 25 m-ohmic resistance at 20 degrees C. When the wire is carrying a current, heat produced by the current causes the temperature of the wire to increase by 27 degrees C.
(a) What is the change in the wire's resistance?
(b) If its original current was 10.0mA, what is its final current?
