I know that the resistance of the tungsten filament depends upon the resistivity of the tungsten metal, the cross section of the filament wire and the temperature of the metal filament. Is there formulation or a set of equations that relates the filament resistance and filament temperature to the DC or RMS current passing through the filament at a specified time? I assume that steady state thermal conditions exist when the filament temperature and filament resistance are calculated.
