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.
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.

A suspension bridge is supported from a height of 30 feet. The length of the wire used to suspend the bridge, from the ground to the top, is 65 feet. What is the angle of elevation from the base of the bridge to the point of suspension?
What is the bridge made of?
The Verrazano-Narrows bridge connects Brooklyn and Staten Island and is named for Giovanni da Verrazzano. The bridge is constructed from concrete pilings, steel wire cables, iron eyebars, steel girders, and steel towers.
What is the cause of resistance and how the resistance of wire can be determind?
The cause of resistance is the opposition to the flow of charges.Resistance occurs due to the collisions between charges inside a substance. The resistivity of a wire can be found out by using a meter bridge or a slide wire 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.

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 is the principle of Carey foster's bridge?
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.
What is the way the Brooklyn bridge made?
The Brooklyn Bridge is a suspension bridge made from wire cable.
Where was the wire for the Brooklyn bridge made?
The wire for the Brooklyn Bridge was primarily made in Germany. John A. Roebling, the bridge's chief engineer, sourced high-quality wire from German manufacturers, which was essential for the bridge's suspension cables. This wire was then shipped to the United States for the bridge's construction in the late 19th century.
What covers the Brooklyn Bridge?
The Brooklyn Bridge is made of wire cable.
Can you use wire to support a bridge?
Yes. They're called suspension bridges. The Golden Gate Bridge outside San Francisco is one of them. The suspension cables are made out of wire. Very thick wire but wire non the less.
What is the Rio-Antirio bridge made out of?
metal concrete wire plastic steel
What is golden gate bridge made out of?
the golden gate bride is made out of 27 572 strands of wire on each cable
