Which metal has highest resistivity class 10?
2 Answers
In Class 10 physics, the metal with the highest resistivity is typically tungsten. Tungsten has a resistivity of about \(5.6 \times 10^{-8} \, \Omega \cdot m\), making it less conductive than many other metals like copper and aluminum. Would you like to delve into the applications or properties of tungsten further?
In Class 10 science, the metal with the highest resistivity is typically **Constantan**.
**Resistivity** is a measure of how strongly a material opposes the flow of electric current. It’s important to note that while metals generally have low resistivity compared to other materials, certain alloys like Constantan (a copper-nickel alloy) are designed to have higher resistivity.
Constantan is used in applications where stable electrical resistance is needed, such as in thermocouples and resistors. Its resistivity is significantly higher than that of pure metals like copper and aluminum.
