일반물리학 2 — Current and Resistance: Problem 51

51 A common flashlight bulb is rated at 0.20 A and 3.2 V (the values of the current and voltage under operating conditions). If the resistance of the tungsten bulb filament at room temperature (\( 20^{\circ}\text{C} \)) is \( 1.1\text{ }\Omega \), what is the temperature of the filament when the bulb is on?
