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.

What is the concept of the kelvin bridge circuit?

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.


What is a Kelvin bridge?

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.


Compare the accuracy of the wheatstone and kelvin double bridge?

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.
