  2. Wheatstone bridge - Wikipedia

    en.wikipedia.org/wiki/Wheatstone_bridge

    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 ]

  3. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    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 .

    List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.

  5. Carey Foster bridge - Wikipedia

    en.wikipedia.org/wiki/Carey_Foster_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 rather than R X. Let ℓ 1 be the null point D on the bridge wire EF in percent.

    en.wikipedia.org/wiki/Post_office_box_(electricity)

    A typical post office box is in a wooden box with a hinged lid and a metal or bakelite panel showing circuit connections. Coils of wire are wound non-inductively, mounted in the body of the box, and have a negligible temperature coefficient. Pairs of ratio arms are each 5 10 20 ohms. Resistance arms contains a number of coils from 1 to 5000 ...

  7. Wien bridge oscillator - Wikipedia

    en.wikipedia.org/wiki/Wien_bridge_oscillator

    Meacham's circuit included a quartz crystal oscillator and a lamp in a Wheatstone bridge. In Meacham's circuit, the frequency determining components are in the negative feed back branch of the bridge and the gain controlling elements are in the positive feed back branch. The crystal, Z 4, operates in series resonance. As such it minimizes the ...

  8. Samuel Hunter Christie - Wikipedia

    en.wikipedia.org/wiki/Samuel_Hunter_Christie

    However, the method went unrecognised until 1843, when Charles Wheatstone proposed it, in another paper [3] for the Royal Society, for measuring resistance in electrical circuits. Although Wheatstone presented it as Christie's invention, it is his name, rather than Christie's, that is now associated with the device.
