1.	Two electric bulbs have tungsten filament of same length. If one of them gives `60 W` and the other `100 W` , thenA. `100 W` bulb has thicker filamentB. `60 W` bulb has thicker filamentC. both filaments are of same thicknessD. it is not possible to get different wattages unless the lengths are different
Answer» Correct Answer - A `P = V^(2)//R` . If `P` is more , `R` is less . `R = rho l // a`. For less `R`, a is more . So the `100 W` bulb has thicker element .
