(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?
