Statement 1 : The temperature dependence of resistance is usually given as R = Ro (1 + α Δt). The resistance of a wire changes from 100Ω to 150Ω when its temperature is increased from 27°C to 227°C. This implies that α = 2.5 × 10–3/°C.
Statement 2 : R = Ro (1+ α Δt) is valid only when the change in the temperature ΔT is small and ΔR = (R – R0) << Ro.
Statement 2 : R = Ro (1+ α Δt) is valid only when the change in the temperature ΔT is small and ΔR = (R – R0) << Ro.
- a)Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1.

(The relation R = R0 (1 +α Δt) is valid for small values of Δt and R0 is resistance at 0°C and also (R – R0) should be much smaller than R0. So, statement (1) is wrong but statement (2) is correct.

+ α(T - To)), where R is the resistance at temperature T, Ro is the resistance at a reference temperature To, and α is the temperature coefficient of resistance.
Statement 2 : The temperature coefficient of resistance is a measure of how much the resistance of a material changes with temperature.
Statement 3 : Materials with a positive temperature coefficient of resistance (positive α) increase in resistance as temperature increases, while materials with a negative temperature coefficient of resistance (negative α) decrease in resistance as temperature increases.
Statement 4 : The temperature coefficient of resistance can be used to determine the resistance of a material at a different temperature than the reference temperature by using the equation R = Ro (1 + α(T - To)).
