  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 .

  4. Voltage divider - Wikipedia

    en.wikipedia.org/wiki/Voltage_divider

    Voltage dividers are used for adjusting the level of a signal, for bias of active devices in amplifiers, and for measurement of voltages. A Wheatstone bridge and a multimeter both include voltage dividers. A potentiometer is used as a variable voltage divider in the volume control of many radios.

    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. 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 ...

  7. Wien bridge oscillator - Wikipedia

    en.wikipedia.org/wiki/Wien_bridge_oscillator

    A Wien bridge oscillator is a type of electronic oscillator that generates sine waves. It can generate a large range of frequencies . The oscillator is based on a bridge circuit originally developed by Max Wien in 1891 for the measurement of impedances . [ 1 ]

    People loved Wesley's first acting gig; the video went viral and has more than 9 million views and nearly 5 thousand comments. I've watched the video at least 5 times and laugh every single time!

  9. Catalytic bead sensor - Wikipedia

    en.wikipedia.org/wiki/Catalytic_bead_sensor

    The catalytic bead sensor consists of two coils of fine platinum wire each embedded in a bead of alumina, connected electrically in a Wheatstone bridge circuit. One of the pellistors is impregnated with a special catalyst which promotes oxidation whilst the other is treated to inhibit oxidation. Current is passed through the coils so that they ...
