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 Carey foster bridge wire made of?
The Carey Foster bridge wire is typically made of a fine platinum or platinum alloy. This wire is used in precision measurements, particularly in electrical resistance experiments, due to its stable and reproducible properties. The choice of platinum ensures high resistance to oxidation and temperature changes, making it ideal for laboratory applications.
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.
What are the applications of Maxwell bridge?
for a joke - Maxwell Bridge is connecting two sides of the Wabash River.
Why low resistance is measured in Carey foster bridge?
Low resistance is measured in a Carey Foster bridge to accurately determine the resistance of a low-resistance conductor, such as a wire or a resistor. The design of the Carey Foster bridge minimizes errors and enhances sensitivity in measurements by using a longer wire, which helps to reduce the impact of contact and lead resistances. This technique allows for precise comparisons between the unknown resistance and a known standard, ensuring accurate results in low-resistance measurements.
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 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.

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.
What will happen if bridge wire is not uniform in Carey foster bridge?
