FAQ

Those who are looking for an answer to the question «Why is tungsten used for filament of electric bulb?» often ask the following questions:

👉 Why is tungsten used for the filament in electric bulb?

The metal tungsten is almost exclusively used for the filament of the electric lamp because it has a very high melting point due to which it does not melt even when it is heated to high temperatures due to the passage of electric current.

Question from categories: electric fuse why is the tungsten used almost exclusively for filament of electric lamps class 10 electric bulb diagram

👉 Why tungsten is used for making filament of electric bulb?

Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point It has very high resistivity so it does not burn easily at room temperature The lamp glows at high temperatures

👉 Why filament of electric bulb is made of tungsten?

Melting Point of filament is very high. The resistance of filament should be high so that it can produce heat and light and its melting point should also be high so that it does not melt at the high temperature at which it is producing light. Answer- (A)

The main reasons why tungsten is used in light bulbs is because it has a high melting point, high electrical resistivity and is far more durable than any other available option. These properties make it suitable since the filament

Mention two reasons on why tungsten is used for making filament of electric bulb. Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point. It has very high resistivity so it does not burn easily at room temperature. The lamp glows at high temperatures.

tungsten is use as bulb filament due to following reasons, having high melting point. prevents from oxidation good conductor of electricity have low resistivity.. hope it will be helpful.. please mark as brainlist answer..

Tungsten is used for making the filaments of electric bulbs because it has a very high melting point. Due to its very high melting point, the tungsten filament can be kept white hot without melting away. Also, tungsten has high flexibility and low rate of evaporation at high temperature.

The reason tungsten is used is because it has the highest melting temperature of any element at 3600K, where as nichrome melts at 1600 K which is almost to cold to give off light (maybe dark red). To generate a lot of heat you need a big resistance.

1 Answer. Tungsten is used for making the filaments of electric bulbs because it has a very high melting point. Due to its very high melting point, the tungsten filament can be kept white hot without melting away. Also, tungsten has high flexibility and low rate of evaporation at high temperature.

1 Answer. (a) Tungsten has a high melting point (3380°C). It does not melt at high temperatures. It retains as much of heat generated, so that it becomes very hot and emits light. (b) Conductors of electric heating devices are made up of alloys because alloys do not oxidise readily at high temperatures, unlike metals.

tungsten is used for making filament of electric lamp because of some of it's amazing properties like it has the highest melting point (3695 K),also lowest vapor pressure, and greatest tensile strength out of all the metals.Because of these properties it is the most commonly used material for light bulb filaments. New questions in Science

Tungsten is used in electric bulb because it has high melting point and it does not oxidize. Thus tungsten filament does not melt even when a large amount of heat is produced due to passage of current through the filament (via heating effect of current).
