0. Incandescent bulbs are designed by keeping in mind that the resistance of their filament increases with the increase in temperature. If at room temperature 100 W, 60 W and 40 W bulbs have filament resistance R100, R60 and R40 respectively, then the relation between these resistance is (NTSE Haryana, Stage-I, 2016-17)
R100 = R40 + R60
R100 > R60 > R40
