A Kelvin bridge (as well called a Kelvin double bridge and in some countries a Thomson bridge) is a measuring instrument used to measure unknown electrical resistors below 1 ohm. It is specifically designed to measure resistors that are built as four terminal resistors.

kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
Kelvin Bridge: This Bridge is a modified version of Wheatstone Bridge and provides greatly increased accuracy in the measurement of low value resistances, generally below 1 ohm.
A Kelvin bridge is a type of electrical circuit used for measuring very low resistances precisely. It minimizes errors caused by the resistance of the connecting leads by using a Wheatstone bridge configuration with additional connections to compensate for lead resistances. This allows for accurate measurement of small resistances in applications such as precision electronics and material testing.
The Kelvin double bridge is more accurate than the Wheatstone bridge because it eliminates errors associated with lead resistance and contact resistance in the circuit. The Kelvin bridge uses four terminals to independently measure and compensate for these errors, resulting in more precise resistance measurements.

A kelvin can be measured using a thermometer.
The Kelvin scale is used to measure temperature using increments of one unit called the kelvin.
In the SI kelvin is the unit for temperature.
The two main types of bridges in electricity are Wheatstone bridge and Kelvin bridge. The Wheatstone bridge is used to measure resistance while the Kelvin bridge is used to measure low resistance values. Both bridges are commonly used in electrical and electronic circuit analysis for accurate measurements and fault detection.
