  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. Carey Foster bridge - Wikipedia

    en.wikipedia.org/wiki/Carey_Foster_bridge

    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 ...

  4. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging ...

  5. Post office box (electricity) - Wikipedia

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

    Education tool for post office box exhibited at Tokyo Denki University. The post office box was a Wheatstone bridge–style testing device with pegs and spring arms to close electrical circuits and measure properties of the circuit under test.

  6. Lattice network - Wikipedia

    en.wikipedia.org/wiki/Lattice_network

    The lattice structure can be converted to an unbalanced form (see below), for insertion in circuits with a ground plane. Such conversions also reduce the component count and relax component tolerances. [6] It is possible to redraw the lattice in the Wheatstone bridge configuration [7] (as shown in the article Zobel network). However, this is ...

  7. Wien bridge - Wikipedia

    en.wikipedia.org/wiki/Wien_bridge

    The Wien bridge is a type of bridge circuit that was developed by Max Wien in 1891. [1] The bridge consists of four resistors and two capacitors . At the time of the Wien bridge's invention, bridge circuits were a common way of measuring component values by comparing them to known values.

  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.

  9. Instructional theory - Wikipedia

    en.wikipedia.org/wiki/Instructional_theory

    An instructional theory is "a theory that offers explicit guidance on how to better help people learn and develop." [1] It provides insights about what is likely to happen and why with respect to different kinds of teaching and learning activities while helping indicate approaches for their evaluation. [2]
