A common flashlight bulb is rated at 0.32 A and 4.3 V (the values of the current and voltage under operating conditions). If the resistance of the bulb filament at room temperature (20°C) is 1.6 Ω, what is the temperature of the filament when the bulb is on? The temperature coefficient of resistivity is 6.4 × 10-3 K-1 for the filament material.
