- Medium resistance
- Low resistance
- Mega-Ohm range resistance
Hide Solution

The Correct Option is C
Solution and Explanation
Kelvin’s double bridge is a modified form of the Wheatstone bridge designed specifically for measuring very low resistance values accurately.
It eliminates the effect of lead and contact resistances that can significantly affect the measurement of small resistances.
By introducing additional ratio arms, the bridge can provide better compensation for such unwanted resistances.
This makes the Kelvin’s double bridge ideal for low resistance measurements, typically in milliohm ranges.
