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


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 :-

#R/X = l/(100-l)#

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

The general wheat-stone bridge is shown below :-
