Question

What is a Wheatstone bridge?​

Answer 1

Answer:

n its basic form, it is a passive electrical circuit which is used to measure an unknown electrical resistance by ratiometric balance of legs (sometimes called arms) of a four-element “bridge circuit” with the unknown resistance as one of the legs, Figure 1. The circuit can be used to compare an unknown resistance Rx with others of a known value. It is sometimes drawn as a square, Figure 2 (especially by CAD programs), but most engineers prefer the diamond shape which shows the functionality more clearly.

Answer 2

Answer:

A Wheatstone Bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component . The Wheatstone Bridge was invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843.
