A potential difference is applied across the filament of a bulb at t =0, and it is maintained at a constant value while the filament gets heated to its equilibrium temperautre. We find that the final current in the filament is one sixth of the current drawn at t = 0. if the temperature of the filament at t = 0 is 20∘C and the temperature coefficient of resistivity at 20∘C is 0.0043∘ /C, find the final temperature of the filament.
