Physics Question from JEE Main 2025 · 22 January, Shift 1

Which of the following resistivity (ρ\rho) vs temperature (TT) curves is most suitable to be used in wire-bound standard resistors?

  • A
    Graph of resistivity rho in ohm centimetre versus temperature T in kelvin, showing an almost horizontal line with slight positive slope.
  • B
    Graph of resistivity rho in ohm centimetre versus temperature T in kelvin, showing a curve rising steeply upward with increasing temperature.
  • C
    Graph of resistivity rho in ohm centimetre versus temperature T in kelvin, showing a rapidly decreasing curve that flattens near the temperature axis.
  • D
    Graph of resistivity rho in ohm centimetre versus temperature T in kelvin, showing a straight line decreasing linearly with temperature.
