JEE Main 202522 Jan, Morning shiftPhysicsEasyCurrent Electricity150× since 2002Which of the following resistivity (ρ)(\rho)(ρ) v/s temperature (T) curves is most suitable to be used in wire bound standard resistors?AOption A. Graph of ρ\rhoρ (Ω\OmegaΩ cm) vs T (K): starts near zero and rises steeply (upward-curving)BOption B. Graph of ρ\rhoρ (Ω\OmegaΩ cm) vs T (K): straight line decreasing with TCOption C. Graph of ρ\rhoρ (Ω\OmegaΩ cm) vs T (K): large value, almost flat line rising very slightly with TDOption D. Graph of ρ\rhoρ (Ω\OmegaΩ cm) vs T (K): very large at low T, falling rapidly and levelling offCheckStep-by-step hintSkip · show solution
