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.
Viva questions on Carey foster bridge?
we can measure the resistance of the given wire using the carey foster bridge / ?
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 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.
When was Carey Foster born?
Carey Foster was born in 1835.
When did Carey Foster die?
Carey Foster died on 1919-02-09.
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.
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

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.
What movie and television projects has Carey Foster been in?
Carey Foster has: Played Jan in "The Lieutenant" in 1963. Played College Girl in "Roustabout" in 1964. Played Pajama Girl in "Pajama Party" in 1964. Played Winter-A-Go-Go Girl in "Winter A-Go-Go" in 1965. Played Dancer in "Point Blank" in 1967.
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.
