What is the final operating temperature of the filament

Reference no: EM13562754

The potential difference across the filament of a lamp is maintained at a constant level while equilibrium temperature is being reached. It is observed that the steady-state current in thelamp is only one-ninth of the currentdrawn by the lamp when it is first turned on. If the temperature coefficient of resistivity for the lamp at 20.0°C is0.00450 (°C)^-1, and ifthe resistance increases linearly with increasing temperature, what is the final operating temperature of the filament?
