The meter bridge shown in the balance position with P Q = l ₁ l ₂ . If we now interchange the positions of galvanometer and cell, will the bridge work? If yes, that will be balanced condition?

Step-by-step solution

For balanced position in a meterbridge Now, if position of G and cell is interchanged, The balance condition still remains the same if the jockey points as the same point as given in the initial condition, for which there is no deflection in the galvanometer or no current will be drawn from the cell. Thus, the bridge will work as usual and balance condition is same, P / Q=l₁ / l₂
