The Wheatstone bridge is the electrical equivalent of two parallel voltage divider circuits. R1 and R2 compose one voltage divider circuit, and R4 and R3 compose the second voltage divider circuit. The output of a Wheatstone bridge is measured between the middle nodes of the two voltage dividers.

Apr 27, 2021 · A Wheatstone bridge consists of four resistors (R 1, R 2, R 3 and R 4) that are connected in the shape of a diamond with the DC supply source connected across the top and bottom points (C and D in the circuit) of the diamond and the output is taken across the other two ends (A and B in the circuit).

Figure 1: The Wheatstone Bridge. Why Wheatstone Bridge? A Wheatstone bridge, also called a null comparator, is used for measuring accurate resistance. In the Wheatstone bridge of Figure 1, R 1, R 2, and R3 are known and R x is the unknown resistance. When the potential (voltage) P1 (see the figure) is the same as potential P2, the bridge is ...

A Wheatstone bridge can be used to measure resistance by comparing the unknown resistor against precision resistors of known value, much like a laboratory scale measures an unknown weight by comparing it against known standard weights. A Kelvin Double bridge is a variant of the Wheatstone bridge used for measuring very low resistances. Its ...

The operation of the Kelvin bridge is very similar to the Wheatstone bridge, but uses two additional resistors. Resistors R 1 and R 2 are connected to the outside potential terminals of the four terminal known or standard resistor R s and the unknown resistor R x (identified as P 1 and P ′ 1 in the diagram).
