If galvanometer and battery are interchanged in balanced wheatstone bridge, then

In the meter bridge experiment, a student observes a balance point at the point at the point J, where AJ=l. The value of R and X are both doubled and then interchanged. What will be the new position of balance point. If in this set up, the galavanometer and battery are interchange at the balance point position, how will the balance point get affected?

Extended Wheatstone Bridge

(i) In a metre bridge, the balance point is found to be at 39.5 cm from the end A, when the resistor Y is of 12.5 Omega . Determine the resistance of X. Made of thick copper strips? (ii). Determine the balance point of the bridge above if X and Y are interchanged. (iii). what happens if the galvanometer and cell are interchanged at the balance point of the bridge ? Would the galvanometer show any current?

Figure 6.64 shows a balanced wheatstone bridge.
