The accuracy of Kelvins double bridge for the measurement of low resis...
Kelvin bridge overcomes the difficulties that arise in a Wheatstone bridge on account of the resistance of the leads and the contact resistances while measuring low valued resistors. The Kelvin double bridge incorporates the idea of a second set of ratio arms-hence the name double bridge and the use of four terminal resistors for the low resistance arms. The second set of ratio arms eliminate the effect of connecting lead resistance.

The accuracy of Kelvins double bridge for the measurement of low resis...
Explanation:
Low Resistance Link:
Kelvin's double bridge uses a low resistance link between standardized test resistances. This low resistance link helps to minimize the errors caused by contact resistance and lead resistance.
Accuracy:
By using a low resistance link, the bridge is able to provide accurate measurements of low resistances. This is because the low resistance link ensures that the resistance of the connecting wires does not affect the measurement accuracy.
Elimination of Errors:
The use of a low resistance link helps to eliminate errors that can occur due to the resistance of the connecting wires. This ensures that the measurement is highly accurate.
Comparison:
In comparison, using two pairs of resistance arms or having medium value resistance in the ratio arms does not necessarily guarantee high accuracy for measuring low resistances. These factors may affect the overall accuracy of the measurement.
Conclusion:
Therefore, the high accuracy of Kelvin's double bridge for measuring low resistance is primarily attributed to the use of a low resistance link between standardized test resistances. This feature helps to minimize errors and ensures precise measurements of low resistances.
