14+ Wheatstone Bridge Diagram. Wheatstone bridge is a simple circuit that is used for accurately measuring the value of an unknown resistor. Samuel hunter christie invented the wheatstone bridge in 1833 and this bridge was improved and popularized by sir charles wheatstone in 1843.
Wheatstone bridge for measuring accurately any electrical resistance wheatstone bridge is widely used. Wheatstone bridge is used to determine the electrical resistance in a circuit. This diagram shows how to connect the rtd to a wheatstone bridge, and then to a.
The ratio of their resistances are the working of the bridge is similar to the potentiometer.
14+ Wheatstone Bridge Diagram. There are two known resistors, one variable resistor and one unknown resistor connected in. In the above diagram, r4 is the unknown arm. The primary benefit of the circuit is its ability to provide extremely accurate measurements. One or more of these legs can be active sensing elements.
