Two conductors, one of copper and the other of iron, are connected in parallel and carry equal currents at 25°C. How many percent of the total current will the copper conductor carry if the temperature is raised to 100°C? The temperature coefficients of resistance at 0 °C are 0.0043 /°C and 0.0063 /°C for copper and iron, respectively.
