First, Kirchhoff’s first law is used to find the currents in junctions B and D:.
Some of the modifications are:. Geophone Hydrophone Microphone Seismometer.

The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low weatstone. Air—fuel ratio meter Blind spot monitor Crankshaft position sensor Curb feeler Defect detector Engine coolant temperature sensor Hall effect sensor MAP sensor Mass flow sensor Omniview technology Oxygen sensor Parking sensors Jembaan gun Speed sensor Speedometer Throttle position sensor Tire-pressure monitoring system Torque sensor Transmission fluid temperature sensor Turbine speed sensor Variable reluctance sensor Vehicle speed sensor Water sensor Wheel speed sensor.
This setup is frequently used in strain gauge and resistance thermometer measurements, as it is usually faster to read a voltage level off a meter than to adjust a resistance to zero the voltage. On the other hand, if the resistance of the galvanometer is high enough that I G is negligible, it is possible to compute R x from the three other resistor values and the supply voltage V Sor the supply voltage from all four resistor values.
The desired value of R x is now dheatstone to be given as:. The primary benefit of the circuit is its ability to provide extremely accurate measurements jembattan contrast with something like a simple voltage divider. Active pixel sensor Angle—sensitive pixel Back-illuminated sensor Charge-coupled device Contact image sensor Electro-optical sensor Flame detector Infrared Kinetic inductance detector LED as light sensor Light-addressable potentiometric sensor Nichols radiometer Optical fiber Photodetector Photodiode Photoelectric sensor Photoionization detector Photomultiplier Photoresistor Photoswitch Phototransistor Phototube Position sensitive device Scintillometer Shack—Hartmann wavefront sensor Single-photon avalanche diode Superconducting nanowire single-photon detector Transition edge sensor Tristimulus colorimeter Visible-light photon counter Wavefront sensor.
In other projects Wikimedia Commons. The equations for this are:. The Wheatstone bridge is the fundamental bridge, but there are other modifications that can be made to measure various kinds of resistances when the fundamental Wheatstone bridge is not suitable. In many cases, the significance of measuring the unknown resistance is related to measuring the impact of some physical phenomenon such as force, temperature, pressure, etc.
The concept was extended to alternating current measurements by James Clerk Maxwell in and further improved by Alan Blumlein around Breathalyzer Carbon dioxide sensor Carbon monoxide detector Catalytic bead sensor Chemical field-effect transistor Electrochemical gas sensor Electrolyte—insulator—semiconductor sensor Electronic nose Fluorescent chloride sensors Holographic sensor Hydrocarbon dew point analyzer Hydrogen sensor Hydrogen sulfide sensor Infrared point sensor Ion selective electrode Microwave chemistry sensor Nitrogen oxide sensor Nondispersive infrared sensor Olfactometer Optode Oxygen sensor Pellistor pH glass electrode Potentiometric sensor Redox electrode Smoke detector Zinc oxide nanorod sensor.
To do so, one has to work out the voltage from each potential divider and subtract jembatam from the other. Schering Bridge Wien bridge. A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuitone leg of which includes the unknown component.
Kelvin bridge Wheatstone bridge. At this point, the voltage between the two midpoints B and D will be zero. Variations on the Wheatstone bridge can be used to measure capacitanceinductanceimpedance and other quantities, jembaatan as the amount of combustible gases in a sample, with an explosimeter.
Electrical meters Bridge circuits Measuring instruments English inventions Impedance measurements. One of the Wheatstone bridge’s initial uses was for the purpose of soils analysis and comparison.
Diode bridge H bridge.
Detecting zero current with a galvanometer can be done to extremely high precision.
