A Carey-foster's bridge is a modified version of the meter bridge (wheatstone bridge or potentiometer). It can be used to find out the average resistance per unit length of the meter bridge wire and hence find out the unknown resistance. It is more accurate and more sensitive than a meter bridge.

WHEATSTONE BRIDGE : A wheatstone bridge is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown compound.Its operation is similar to the original potentiometer. METER BRIDGE : A uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a wheatstone bridge or of a potentiometer.
A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.
End correction in a meter bridge refers to the added resistance due to the non-zero dimensions of the connecting wires or strips at the ends of the bridge. This added resistance needs to be accounted for when using the meter bridge for precise measurements. Calculating the end correction helps ensure accurate results when determining unknown resistances.
The end correction of a meter bridge can be measured by comparing the balance point of a known standard wire to the balance point of an unknown wire on the meter bridge. The difference in lengths between the two balance points is equal to the end correction.
Van Metre Ford Stone Bridge was created in 1832.
In a meter bridge, the jockey is used to slide along the wire to make contact with the resistance wire and balance the bridge by finding the null point. This allows for accurate measurement of unknown resistance by comparing it with a known resistance.
The cable-stayed bridge is a type of bridge that is optimal for spans longer than is practical for cantilever bridges, and shorter than is economical for suspension bridges.
