Question

Why is the Carey Foster Bridge so sensitive?

Answer 1

In order to answer this question, first we will discuss the reason behind why Carey Foster Bridge is so sensitive. And then we will discuss the Carey Foster Bridge. After that we will also discuss the purposes of Carey Foster Bridge. And atlast we will also discuss how Carey Foster Bridge is similar to Wheatstone bridge.

Complete answer:
Because it's used to measure the tiniest decimal change in resistance, the Carey Foster bridge is extremely sensitive. The length of the wire used in the Carey Foster bridge determines its sensitivity.
The Carey Foster bridge is a bridge circuit in electronics that is used to monitor medium resistances or slight variations between two high resistances. Carey Foster created it as a variation on the Wheatstone bridge. In his 1872 work "On a Modified Form of Wheatstone's Bridge, and Methods of Measuring Small Resistances," he described it for the first time.
In simple words, we can say that- Carey foster bridge is a bridge circuit that can calculate medium resistances or compare and measure two large/equal resistance values with small fluctuations. It's a tweaked version of Wheatstone's bridge circuit. It's also known as the "small resistances" strategy.
The Carey Foster bridge is an electrical circuit for determining medium resistances. It functions on the same basis as a Wheatstone bridge, namely, the null indication principle. Carey Foster was the one who came up with the idea.

Note: The Carey Foster bridge is an electrical circuit for determining medium resistances. It functions on the same basis as a Wheatstone bridge, namely, the null indication principle. Carey Foster was the one who came up with the idea. The operation of the Carey Foster Bridge is similar to that of the Wheatstone Bridge.
