The resistance of an incandescent light bulb filament is not constant. As the temperature increases, its resistance also increases, because the vibration of the atoms in the metal (Tungsten) at high temperature interrupt the flow of electrons. However, we can apply Ohm's law at room temperature considering the resistance as constant. The resistances of incandescent light bulbs 100W, 60W, and 40W at room temperaure are represented by R100w, ROW and R40w, respectively. Which of the following statement is true? O a. > ROW Select one: 1 R100W Row 1 1 R100W ROW O c. R100W > Row > R40W d. R100w = Roow + R20W O b. + R40W
