Step 1

The ratio of ‘balancing lengths’ seen on the bridge wire is used for the measurement of the ratio of the two resistors which are taken for comparison in the meter bridge setup.

In the above mentioned problem, two equilibrium conditions will have to be specified.

  • Translational equilibrium
  • Rotational equilibrium.

 

 

From the free body diagram of the ladder, that the translational equilibrium conditions are illustrated as follows
