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.

Can we connect rheostate insetad of p and q in Carey foster bridge?
Yes, but the ratio of P and Q should be kept equal.
What is the concept of the kelvin bridge circuit?
Kelvin Bridge: This Bridge is a modified version of Wheatstone Bridge and provides greatly increased accuracy in the measurement of low value resistances, generally below 1 ohm.

Applications of Carey foster's bridge?
The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
What is the difference between the Carey foster bridge and meter bridge?
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
What is the difference between a potentiometer and a Carey Foster's bridge?
effective length of carey foster's bride is more ; hence more accurete

When was Carey Foster born?
Carey Foster was born in 1835.
When did Carey Foster die?
Carey Foster died on 1919-02-09.
Can we connect rheostate insetad of p and q in Carey foster bridge?
Yes, but the ratio of P and Q should be kept equal.
What is the principle of Carey foster's bridge?
the principle of wheatstone bridge is,there is a potential fall is directly proportional to the length of the wire, and this fall is also equalt to the fall accross the resistances applied in parallel to the battery. It is a form of wheatstone bridge.
Why standard 1 ohm resistance used in Carey foster bridge experiment?
In the Carey Foster bridge experiment, a standard 1-ohm resistance is used as a reference to ensure accurate measurements of unknown resistances. This value is convenient because it simplifies calculations and allows for clear comparisons with the unknown resistances being tested. The use of a 1-ohm resistor also helps minimize errors due to voltage drops, making the measurements more reliable and precise. Additionally, the 1-ohm standard provides a uniform baseline for calibration in various experimental setups.
Who made the millennium bridge?
the millennium bridge is designed by Foster + Partners
Who won the battle of Goldsboro Bridge?
John G. Foster
