In a 4-wire Kelvin measurement system, sense resistors are essential for accurate voltage measurement across a test resistance. They ensure minimal voltage drop on the sense lines, allowing for precise readings of low resistance values. The sense resistors are placed in the measurement circuit to eliminate the effects of lead resistance, enhancing measurement accuracy. This configuration is critical in applications requiring high precision, such as semiconductor testing and material characterization.
