The only reliable way to measure resistance is to remove the component from the circuit completely and test it. If this isn't something you're able to do, you may have to resort to Ohm's Law (R=V/I) to find the value. Test engineers must implement various measurement mitigations, such as using a. Measurement of Low Resistance: Low resistances (<1Ω) are measured using methods like Kelvin's Double Bridge to minimize error from contact resistance. Measurement of Medium Resistance: For medium resistances (1Ω to 100kΩ), the Wheatstone Bridge Method is a standard, balancing the circuit to detect. The article covers various methods for measuring electrical resistance, including low resistance measurement using voltmeters and ammeters, ohmmeter functionality and calibration, high resistance measurement techniques using voltmeters, and precision measurement using the Wheatstone bridge.
