Determine the temperature of the hot filament

Reference no: EM13290915

A certain lightbulb has a tungsten filament with a resistance of 18.0 when cold and 138 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. Assume an initial temperature of 20.0°C. ___________________ °C
