Q4 The resistivity of a coil of copper wire (1.8 km Length and 0.014 m diameter) at 18'C is 1.7 * 10* 2m. The temperature of the same wire is increased and the resistance at this temperature is 0.26 2. If the temperature coefficient of resistance of copper is 0.004/"C at 18'C, determine the temperature to which the coil has risen.
