(a) How much current flows in a 100 watt bulb when lit? Assume 120 volts and assume DC voltage. (b) What is the resistance of a 100 watt light bulb when lit? Assume 120 volts and a tungsten filament temperature of 1200° C when lit. (c) How much current flow in the bulb when it is first turned on and the temperature of the filament is 20° C? Use α-5.36 x 10-3 Co.1 for tungsten.
