A Kelvin bridge is a device used for the high-precision measurement of resistance values.
It is an improved version of the Wheatstone bridge, operating by comparing the unknown resistance value with a known one. Its principle involves four resistors and an ammeter, notably a Thomson ammeter for high sensitivity. It also uses standard resistors less affected by temperature changes, thus minimizing errors from temperature variations. A characteristic feature is its broad measurement range, enabled by adjusting the variable resistor.
Kelvin bridges are applied in various fields, including electrical circuit design, manufacturing, precision measurement, and research and development. For example, they measure component resistance values in circuit design and are used for component quality control in manufacturing processes.
