Detailed Solution

Statement-I: True. In a balanced Wheatstone bridge, if the cell and galvanometer arms are interchanged, the reading of the galvanometer remains unchanged.

Statement-II: True. For a balanced Wheatstone bridge, the current detected by the galvanometer is indeed zero. This is because in a balanced Wheatstone bridge, the potential difference across the galvanometer arm is zero, resulting in no current flow through it.

Therefore, both statements are true.
