1. Find the resistance of a conductor at 500 degrees Celsius given that its temperature coefficient at 200 degrees Celsius being 1/420 per °C and resistance at 420 °C being 200 ohms. 2. 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.

1. Find the resistance of a conductor at 500 degrees Celsius given that its temperature coefficient at
200 degrees Celsius being 1/420 per °C and resistance at 420 °C being 200 ohms.
2. 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.
