It is found that the resistance of a coil of wire increases from 40 ohm at 15°C to 50 ohm at 60°C. Calculate the resistance temperature 3. A tungsten lamp filament has a temperature of 2,050°C and a resistance of 500 when taking normal working current. Calculate the resistance of the filament when it has a temperature of 25°C. Temperature coefficient at 0°C is 0.005/°C. coefficient at 0°C of the conductor material.
