What is the formula for converting the resistance of a 100-ohm platinum RTD to a temperature reading in Celsius (°C)?
A. T = (Rt – R0) / (0.00385 * R0)
B. T = (Rt / R0 – 1) / 0.00385
C. T = (Rt – R0) / (0.00385 * Rt)
D. T = (Rt / R0 – 1) / (0.00385 * R0)
Answer:A

Explanation: To convert the resistance of a 100-ohm platinum RTD to a temperature reading in Celsius (°C), use the formula T = (Rt – R0) / (0.00385 * R0), where Rt is the measured resistance and R0 is the resistance at 0°C.
