The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
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.
for a joke - Maxwell Bridge is connecting two sides of the Wabash River.
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
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.
The Schering bridge, while useful for measuring capacitance and loss, has several disadvantages. It requires precise calibration and can be sensitive to changes in temperature and humidity, affecting accuracy. Additionally, the bridge configuration can be complex, making it less user-friendly for some applications. Finally, it may not be suitable for very high-frequency measurements, limiting its versatility in certain situations.

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.

effective length of carey foster's bride is more ; hence more accurete
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor.

A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
to measure unknown resistance
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.
Yes, but the ratio of P and Q should be kept equal.
