Two electric bulbs have tungsten filament of same length. If one of them gives `60 W` and the other `100 W` , then

Two electric bulbs have tungsten filaments of the same length. If one of them is rated 60 watt and the other 100 watt then which one has thicker filament wire?

The tungsten filaments of two electric bulbs are of the same length. If one of them gives 25 W power and the other 60 W power, then

The tungsten filaments of two electric bulbs are of the same length. If one of them gives 25 W power and the other 60 W power, then

The filament of an electric bulb is made of tungsten.

A 100W bulb and a 25W bulb are desigened for the same voltage. They have filaments of the same length and material. The ratio of the diameter of 100W bulb to that of the 25W bulb is

Two electric bulbs , rated for the same voltage , have powers of 200 W and 100 W , respectively. If their resistances are r_(1) and r_(2) , respectively , then

Two electric bulbs , rated for the same voltage , have powers of 200 W and 100 W , respectively. If their resistances are r_(1) and r_(2) , respectively , then

If two electric bulbs have 40 W and 60 W rating at V 220 , then the ratio of their resistances will be
