Find the final temperature of the filament

Assignment Help Physics
Reference no: EM131163084

The potential difference across the filament of a light bulb is kept constant while the filament heats up to its final equilibrium temperature. The current in the filament drops to a tenth of its original value at room temperature. If the temperature coefficient of resistivity of the filament is 0.0045 (oC)-1 and the resistivity increases linearly with temperature, find the final temperature of the filament.
