The limitation of the wheatstone is that it may give inaccurate readings if not balanced.
Wheatstone's bridge
He invented the Concertina, and he probably invented the Wheatstone Bridge, which didn't span the Volta, because the current was too weak!
A Wheatstone Bridge is used to measure resistance of an electrical / electronic component. The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter! It uses a completely-different method of measuring resistance and is significantly more accurate than a multimeter. The purpose of the very sensitive galvanometer is to detect when the Bridge circuit is 'balanced', by sensing the current (not voltage!) passing through it. When no current flows, the Bridge is balanced.

Resistance is usually measured using an ohmmeter, however if very high precision is needed a wheatstone bridge is used.
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.

kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
The wheatstone bridge is an instrument used to measure electrical resistance by means of balancing a bridge circuit. The bridge circuit contains two legs, one of which contains the unknown resistance. Variations in wheatstone bridge can be employed to measure inductance, capacitance, and impedance also.

At a balanced condition the voltmeter connected across the wheatstone bridge will be zero.

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.

An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.

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.
