A. ΔT = (R1 – R2) / (R0 * α)
B. ΔT = (R1 / R2 – 1) / (R0 * α)
C. ΔT = (R1 – R2) / (R0 * (α1 + α2) / 2)
D. ΔT = (R1 / R2 – 1) / (R0 * (α1 + α2) / 2)
Answer:C

Explanation: The formula for calculating the temperature difference between two RTDs with different resistance values is ΔT = (R1 – R2) / (R0 * (α1 + α2) / 2), where R1 and R2 are the resistance values of the two RTDs at a specific temperature, R0 is the reference resistance at 0°C, and α1 and α2 are the temperature coefficients of resistance for the two RTDs.
