Acommon flashlight bulb is rated at 0.40 a and 3.0 v (the values of the current and voltage under operating conditions). if the resistance of the bulb filament at room temperature (20°c) is 1.32, what is the temperature of the filament when the bulb is on? the temperature coefficient of resistivity is 5.4 x 10c material. for the filament number units the number of significant digits is set to 2; the tolerance is +/-2%
