In an experiment of Wheatstone bridge, if the positions of cells and galvanometer are interchanged, then the balance points will

When Wheatstone bridge is balanced, $\dfrac{R_1}{R_2}=\dfrac{R_3}{R_4} or \dfrac{R_1}{R_3}=\dfrac{R_2}{R_4}$

If the galvanometer is replaced with a cell in balanced Wheatstone bridge, the condition for balanced bridge will be unchanged. i.e $\dfrac{R_1}{R_2}=\dfrac{R_3}{R_4}$. In balanced condition no current pass through the galvanometer. Thus, the null points will remian same.
