Which of the following has the highest value of resistivity?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Nichrome.
Nichrome has the highest value of resistivity.
Nichrome is a nickel-chromium alloy mostly used in heating elements. It is often chosen for its resistance to oxidation and high-temperature stability. Nichrome wire is often used as a resistance wire in electronics and electrical components.
Silver is known for having a very low resistivity, making it an excellent conductor. It has one of the lowest resistivity values among common materials.
Chromium has a higher resistivity compared to silver and is typically used for its other properties, such as corrosion resistance.
Iron has a higher resistivity compared to silver and is generally considered a poorer conductor.
