  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

    In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.

  4. 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 ...

  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.

  6. Post office box (electricity) - Wikipedia

    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. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    The suggested setting for the configuration shown, is with R1 = R2, and R3 around the middle of the range of the RTD. Looking at the Wheatstone bridge circuit shown, the voltage drop on the lower left hand side is V_rtd + V_lead, and on the lower righthand side is V_R3 + V_lead, therefore the bridge voltage (V_b) is the difference, V_rtd − V ...
