Carry foster bridge

carry foster bridge Carry foster bridge the carey foster bridge is an electrical circuit that can be used to measure very small resistances it works on the same principle as wheatstone’s bridge, which consists of four resistances, p, q, r and s that are connected to each other as shown in the circuit diagram in figure 1.

Anna university - physics practical , carey foster bridge - to determine specific resistance of the given coil video prepared by : kongunadu college of engi. Using the bridge one can calculate the resistance of the wire from which the specific resistance ρ of the material of wire can be obtained the carey-foster bridge is a modified form of meter bridge.

In electronics, the carey foster bridge is a bridge circuit used to measure medium resistances, or to measure small differences between two large resistances it was invented by carey foster as a variant on the wheatstone bridge.

The carey foster bridge is named after him: it is used to measure very low resistances, although it can be used to find, for example, small differences between large resistances the bridge is in two parts: a slide wire, connected by thick copper cables to a holder for standard resistances. Carey foster bridge introduction the carey foster bridge is an electrical circuit that can be used to measure very small resistances it works on the same principle as wheatstone’s bridge, which consists of four resistances, p, q, r and s that are connected to each other as shown in the circuit diagram in figure 1.

Carey foster bridge is very sensitive and we can even measure the decimal value of resistancesuppose we have to find the value of some unknown resistance of about 1000 ohms with a meter bridge wire of say 40 ohms resistance then the bridge will not be so sensitive.

The carey foster bridge is a modified form of the meter bridge in which the effective length of the wire is considerably increased by connecting a resistance in series with each end of the wire this increases the accuracy of the bridge.

The carey foster bridge is used for measuring the low resistance or for the comparison of two nearly two equal resistances the working principle of the carey foster bridge is similar to the wheatstone bridge.

The carey foster bridge in the picture is from denison university, and was made by leeds and northrup of philadelphia in the 1903 l & n booklet describing the bridge there is an engraving of it with the name morris e leeds & co, phila, the name of the original company.
