A copper wire has a resistance of 25 milliohms at 20⁰C. When the wire is carrying current, heat produced by the current causes it's temperature to increase by 27⁰C. What is the change in the wire's resistance? [take temperature coefficinet of resistivity of copper, α = 6.8 x 10^-3 ]

• A.1.2 milliohms
• B.11.3 milliohms
• C.2.3 milliohms
• D.4.6 milliohms
