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 primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider ). [ 1 ]
The two remaining arms are the nearly equal resistances P and Q, connected in the inner gaps of the bridge. A standard Wheatstone bridge for comparison. Points A, B, C and D in both circuit diagrams correspond. X and Y correspond to R 1 and R 2, P and Q correspond to R 3 and R X. Note that with the Carey Foster bridge, we are measuring R 1 ...
The best-known bridge circuit, the Wheatstone bridge, was invented by Samuel Hunter Christie and popularized by Charles Wheatstone, and is used for measuring resistance. It is constructed from four resistors, two of known values R 1 and R 3 (see diagram), one whose resistance is to be determined R x , and one which is variable and calibrated R 2 .
A Maxwell-Wien bridge. A Maxwell bridge is a modification to a Wheatstone bridge used to measure an unknown inductance (usually of low Q value) in terms of calibrated resistance and inductance or resistance and capacitance. [1] When the calibrated components are a parallel resistor and capacitor, the bridge is known as a Maxwell bridge.

A Wheatstone bridge is a configuration of four balanced resistors with a known excitation voltage applied as shown below: Excitation voltage V EX {\displaystyle V_{\text{EX}}} is a known constant and output voltage V o {\textstyle V_{o}} is variable depending on the shape of the strain gauges.
We live in a world where anyone can file a lawsuit for any reason. Fortunately, a fair and impartial judicial process exists to find the truth, and Mr. Combs is confident he will prevail in court.
Video footage of the rockslide shows the rocks tumbling down along with parts of mountain onto the road in a cloud of dust. The video was recorded by Sierra Wright, who told Storyful she made the ...
