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.

Where can one purchase an Auto Transformer?
One can purchase an Auto Transformer from websites like Mastech Power Supply, Amazon, Ali Express, RS-Online, eBay, Foster Transformer, Farnell and Alibaba.
What is end resistance in Carey foster bridge?
End resistance in a Carey Foster bridge refers to the resistance encountered at the terminals of the bridge when measuring the resistance of a conductor. It arises from the contact resistance at the junctions where the measuring leads connect to the bridge and the resistor being tested. This resistance can affect the accuracy of the measurements, so it is typically minimized or compensated for in precise applications. The design of the Carey Foster bridge helps to balance and measure small resistance changes effectively, despite the presence of end 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.
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 a potentiometer and a Carey Foster's bridge?
effective length of carey foster's bride is more ; hence more accurete
WHY CAREY FOSTER BRIDGE IS MORE ACCURATE AND SENSITIVE THAN METER BRIDGE?
The Carey Foster Bridge is more accurate and sensitive than the meter bridge due to its design, which minimizes errors caused by contact resistance and wire resistance. It employs a longer bridge length and a finer scale, allowing for better resolution in measurements. Additionally, the Carey Foster Bridge uses a differential method to measure unknown resistances, enhancing its sensitivity and reliability in determining precise resistance values. This makes it particularly effective for experiments requiring high accuracy.
Who invinted the Manhattan bridge?

What will happen if bridge wire is not uniform in Carey foster bridge?
If the bridge wire in a Carey Foster bridge is not uniform, it can lead to inaccurate measurements of resistance. Variations in the wire's diameter or resistivity can cause discrepancies in the voltage drop across the bridge, resulting in erroneous readings. This non-uniformity may also affect the balance of the bridge circuit, hampering its ability to achieve precise null points. Consequently, the reliability and accuracy of experimental results would be compromised.
