At a balanced condition the voltmeter connected across the wheatstone bridge will be zero.
When the resistance in all four are equal
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.
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.

You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
There are several ways of doing this, but it depends on what information you have to start with. One way is to find the impedance, using a voltmeter and an ammeter (impedance will be the product of the two readings), and the resistance using an ohmmeter (or, better still, a Wheatstone Bridge) and, then, use the equation:cos (phase angle) = resistance / impedance
A meter bridge is used in some cases for precise resistance measurements. It can be more accurate than using a voltmeter and ammeter because it eliminates errors from contact resistance and internal resistance of the instruments. This method allows for more accurate determination of resistance by comparing two resistance values directly.

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.

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.
