Incandescent bulbs are designed by keeping in mind that the resistance – InterviewSolution

1.	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, the relation between these resistance is
Answer» 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 $R_{100}, R_{60} and R_{40}$ , respectively, the relation between these resistance is
