Question

in a balanced wheatstone network the resistances in the arm q and S are interchanged

Answer 1

then what we have to find post full question

Answer 2

Q) In a balanced Wheatstone’s network, the resistances in arms Q and S are interchanged. As a result of this

1) Galvanometer and the cell must be interchanged to balance

2) Galvanometer shows zero deflection

3) Network is not balanced

4) Network is still balanced

Answer: 4)
