In a Resistance Temperature Detector (RTD), the injection of current is used to measure resistance, which varies with temperature. A known current is passed through the RTD, and the resulting voltage drop across it is measured. This voltage is then used to calculate the resistance of the RTD, allowing for precise temperature determination based on the RTD's calibration curve. Proper current injection is crucial to avoid self-heating, which can lead to inaccurate readings.
