Why is tungsten used in fuse?

It is because tungsten has a very high melting point. If it is used as a fuse wire, then it will not melt even when large amount of current is passed through it , and the appliance will be damaged.

Why is tungsten metal is used in bulbs but not in fuse wires?

Because tungsten has a high melting point it is used in blubs. It cannot be used in fuse wires because in fuse wires the material must have a low melting point.

Why is tungsten suitable for making the filament of a 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.

What would happen to an electric circuit if the fuse wire is made of tungsten?

If tungsten is used as a fuse wire, it will not melt if the current goes beyond 15A, and it will fail to safeguard appliances like refrigerator, AC etc. which will eventually cause damage to the appliances and other circuit elements.

Why is tungsten metal used to make a solenoid type coil in an electric bulb?

The solenoid type coil of bulb has high resistivity and very high melting point. When current is passed through the bulb, solenoid type coil of bulb gets heated to high temperature (upto 3400 °C) and starts glowing. Hence, tungsten metal is used to make a solenoid type coil in an electric bulb.

Is tungsten a conductor of electricity?

The movement of electrons is the reason for good conductivity property shown by metals. Thus, we can say that Tungsten has a high melting point, and it has high resistivity towards heat. Tungsten is a poor conductor of electricity even though it is a metal. But at high temperatures, it will conduct electricity.

Why is tungsten used?

Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.

Is tungsten a good conductor of electricity?

What material is fuse wire made of?

Q13) Name the material of a fuse wire. Solution: Fuse wire is made of alloy of lead and tin having low melting point of 200°C.
