In the relation R = R° (1 + α Δt) , ( here R and R° represents resistances), sometimes we directly use Δt as difference in the given temperatures while sometimes we have to assume the resistance at 0°C and then apply the values. Why and when do we have to do so?

Here,R = R° (1 + α Δt) R is the resistance at reference temperature Thus in order, what we have to find the formula will became The formula will also be R=R' (0-0')
