336. assignment (temperature coefficient of resistance)
6) A conductor of diameter 0.5 cm is 10,000 m long.
Calculate the resistance of the wire when it is heated to 300 °C given that the wire is initially at room temperature of 20 °C and its coefficient of resistance is ro = 1.72 x10^-8 Ohm m. The temperature coefficient of resistance alpha = 3.9 x 10^-3 1/°C at room temperature.
