The resistance of an RTD is measured with a DMM that produces an excitation current of 5mA. The measured resistance is 92.5Ω. Find the temperature of the RTD if it has the following parameters: R0 = 100Ω, T0 = 0°C, α0 = 0.00385 C-1. Also, find the power dissipated in the RTD during the measurement. What is the smallest value of dissipation constant such that the temperature measurement error due to self heating is less than 0.5°C?
