Two 48 V batteries are connected in series with a tungsten filament, as used in some lightbulbs. When initially turned on, the filament has a resistance of 12 2. After the filament reaches its operating temperature, it dissipates power at a rate of 75 W. Calculate the change in the resistance of the filament.
