A certain lightbulb has a tungsten filament with a resistance of 18.4 when at 20.0°C and 141 2 when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here. Find the temperature of the hot filament. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.
