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

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 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 filamet of an electric lamp, has a length of 0.25 m and a diameter of 6xx10^(-5) m. The power rating of the filament is 0.8, estimate the steady temperature of filament. Stefan's constant =5.67xx10^(-8) W//m^(-2)//K^(4) .

Give scientific reasons: The filament of an electric bulb is made of tungsten.

Two electric bulbs A and B are rated as 60 W and 100 W. They are connected in parallel to the same source, then

Two electric bulbs, one of 200 V, 40 W and other of 200V, 100 W are connected in a domestic circuit. Then

An electric bulb marked 25 W and 100 V is connected across 50 V supply . Now its power is .

An electric bulb marked 25 W and 100 V is connected across 50 V supply . Now its power is .
