JEE Main 2025 — Current Electricity Question with Solution
From: JEE Main 2025 (Online) 22nd January Morning Shift
Question
Which of the following resistivity ( ) temperature ( T ) curves is most suitable to be used in wire bound standard resistors?
Choose an option
Show full solutionCorrect option: D
Step-by-step explanation
We use Nichrome, manganin and constantan to make standard (reference) wire bound resistors their resistivity is less dependent on temperature. So vs T curve will not show any sharp change.
Hence, option 4 is correct.
