Best Answer

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.

How can accuracy be improved?

Accuracy can be improved by ensuring data is collected correctly and without errors, using reliable sources, double-checking information, and employing fact-checking methods. Implementing clear communication and setting standard procedures can also help enhance accuracy in various tasks. Regular training and feedback can aid in reducing mistakes and improving overall accuracy.


How can you help ensure the accuracy of this measurements?

To ensure accuracy in measurements, use calibrated instruments, follow proper measurement techniques, double-check measurements when possible, and eliminate sources of error such as parallax or environmental factors. Regularly calibrate equipment and follow standardized procedures to maintain accuracy over time.


What if the Final DO is higher than Initial DO?

If the Final DO is higher than the Initial DO, it may indicate an input error or sensor calibration issue. It may also suggest that the water has been aerated or oxygenated since the initial measurement. It is important to double-check the measurements and the calibration of the equipment to ensure accuracy.


What is the theory of kelvin's double bridge experiment?

Kelvin's double bridge experiment is a method used to measure low resistances accurately. It combines the principle of Wheatstone bridge with Kelvin's methodology to nullify the effects of lead resistance. By using two ratio arms and a ratio set, this setup allows for highly precise measurements of resistance.


A device used to compare mass of an object to a known mass?

A balance scale is typically used to compare the mass of an object to a known mass. The unknown mass is placed on one side of the scale while the known mass is placed on the other side, and the balance is used to determine if the masses are equal or not.
