< b="" />Explanation:< />
The correct answer is option 'C', tungsten.
< b="" />Filament of a bulb:< />
The filament of a bulb is the thin wire or thread-like structure that is present inside the bulb and emits light when an electric current passes through it. It is the most important part of an incandescent bulb as it produces light by getting heated up.
< b="" />Composition:< />
The filament is made up of tungsten. Tungsten is a chemical element with the symbol W and atomic number 74. It is a dense, hard, and brittle metal with a very high melting point. Tungsten is known for its high resistance to heat and electricity, making it an ideal material for the filament of a bulb.
< b="" />Reason for using tungsten:< />
There are several reasons why tungsten is used for the filament of a bulb:
1. High melting point: Tungsten has an extremely high melting point of about 3,410 degrees Celsius. This allows the filament to become white-hot and emit bright light without melting or vaporizing.
2. High resistance: Tungsten has a high electrical resistance. When a current passes through the filament, it heats up due to the resistance, and this heat causes the filament to glow and emit light.
3. Durable: Tungsten is a very strong and durable metal. It can withstand the high temperatures and stress caused by the heating and cooling cycles in a bulb without breaking or deforming.
4. Efficient: Tungsten is an efficient material for producing light. It has a high light output per unit of electrical energy consumed, making it an energy-efficient choice for bulbs.
< b="" />Other options:< />
- Aluminium: Aluminium has a relatively low melting point and is a good conductor of electricity. However, it is not suitable for use as a filament in a bulb as it would melt quickly and not emit enough light.
- Chromium: Chromium is a metallic element that is known for its corrosion resistance and shiny appearance. It has a high melting point but is not commonly used as a filament material in bulbs.
- Platinum: Platinum is a precious metal that has a high melting point and is resistant to corrosion. While platinum could be used as a filament material, it is much more expensive than tungsten and not commonly used in regular incandescent bulbs.
In conclusion, the filament of a bulb is made up of tungsten due to its high melting point, high resistance, durability, and efficiency in producing light.
The correct answer is option 'C', tungsten.
