Some possible sources of error in a Wheatstone bridge experiment include resistance changes due to temperature variations, imperfect contact points in the circuit, inaccuracies in the components used, and electrical noise interference. Proper calibration, careful handling of components, and shielding against external interference can help reduce these errors.

What did Charles wheatstone inventions?
Charles Wheatstone invented the concertina, a small musical instrument similar to an accordion. He also invented the Wheatstone Bridge, a device used to measure electrical resistance accurately. Additionally, Wheatstone contributed to the development and improvement of the telegraph system.
Limitations of the wheatstone bridge?
The Wheatstone bridge can be sensitive to environmental factors like temperature changes and can be affected by resistance variations in the arms of the bridge. It requires precise resistor values for accurate measurements and can be limited in its ability to measure very small changes in resistance.
What is Difference between ohmmeter and Wheatstone's bridge?
An ohmmeter is a device used to measure the resistance of a component or circuit by passing a current through it and measuring the voltage drop. In contrast, a Wheatstone's bridge is a circuit used to measure an unknown resistance by balancing it against known resistances in a bridge configuration, without passing a current through the unknown resistor. Wheatstone's bridge is more accurate for precise resistance measurements compared to an ohmmeter.
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.
What happens when unknown resistance is changed to other armin wheatstone bridge?
Changing the unknown resistance in a Wheatstone bridge will result in an imbalance in the circuit, causing a potential difference across the bridge. This potential difference can be used to determine the new value of the unknown resistance by adjusting other known resistances until the bridge is balanced again.
Why using wheatstone bridge in transducer?
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
What is the conclusion for the wheatstone bridge experiment?
This lab effectively showed how the Wheatstone bridge provides a mechanism to calculate an unknown resistance using the known relationships given through the resistivity correlation to length. It demonstrated how to set-up a Wheatstone bridge and how to manipulate a Wheatstone bridge in a laboratory setting. In addition, the lab provided a demonstration of the aforementioned linear relationships. Although significant error existed in this lab, the results still reflect the relationships governing the Wheatstone bridge sufficiently for understanding in an experimental contextual environment unknown resistance using the known relationships given through the resistivity correlation to length.It demonstrated how to set-up a Wheatstone bridge and how to manipulate a Wheatstone bridge in alaboratory setting.

What is the difference between Wheatstone bridge and meter bridge?
WHEATSTONE BRIDGE : A wheatstone bridge is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown compound.Its operation is similar to the original potentiometer. METER BRIDGE : A uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a wheatstone bridge or of a potentiometer.
