Detailed Solution
Download Solution PDFThe correct answer is NichromeKey Points
- Nichrome is an alloy typically made from nickel, chromium, and iron.
- It has a very high electrical resistivity compared to metals like copper, aluminium, or mercury.
- Nichrome is commonly used in heating elements due to its ability to withstand high temperatures and resist oxidation.
Additional Information
- Copper:
- Copper is known for its excellent electrical conductivity and has very low resistivity.
- It is widely used in electrical wiring.
- Aluminium:
- Aluminium has a higher resistivity than copper but is still a good conductor of electricity, making it suitable for use in power transmission lines.
- Mercury:
- Mercury is a liquid metal at room temperature and has relatively high resistivity compared to solid metals like copper and aluminum, but it is still lower than that of nichrome.
