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.

kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
At a balanced condition the voltmeter connected across the wheatstone bridge will be zero.
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.
