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.

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.
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.
Why should jockey not be pressed when it is moved in Carey foster's bridge?
When Jockey is pressed the length of conductor increases due to elasticity. Since resistance is proportional to length the resistance of the conductor also increases. So the voltage drop per unit length alters from its standard value. It causes error in our reading.

we can measure the resistance of the given wire using the carey foster bridge / ?
What is the function of a Carey foster bridge?
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.
