# How can i calculate resistance of a wire?

Mar 20, 2018

Using a set up known as meter bridge we can easily find the Resistance of a wire.

#### Explanation:

The meter bridge works on the principle of wheat-stone bridge.

For the meter bridge shown above the relation from wheat stone bride principle comes out to be :-

$\frac{R}{X} = \frac{l}{100 - l}$

Thus, the unknown resistance $X$ is calculated easily.

The general wheat-stone bridge is shown below :-
