JEE MAIN - Physics (2017 (Offline) - No. 8)
Which of the following statements is false?
Kirchhoff’s second law represents energy conservation.
Wheatstone bridge is the most sensitive when all the four resistances are of the same order of
magnitude.
In a balanced wheatstone bridge if the cell and the galvanometer are exchanged, the null point is
disturbed.
A rheostat can be used as a potential divider.
Explication
There is no change in null point, if the cell and the
galvanometer are exchanged in a balanced wheatstone
bridge.
