Question

what do you understood from the given experiment shown in the figure also write working principle rule​

Answer 1

Explanation:

The principle of working of Metre bridge is wheat stone bridge principle and it is used to find the resistance of an unknown conductor or to compare two unknown resistance

b) In meter bridge balance condition is given by

S

R

=

100−l

When X is connected in parallel with S equivalent resistance in that arm.

=

S+X

New balanced condition is given by
