हिन्दीThe metre bridge shown is in balance position with \( \frac{P}{Q} = \frac{l_1}{l_2} \). If we now interchange the positions of galvanometer and cell, will the bridge work? If yes, what will be balance condition?
Correct answer · Option 1
yes, \( \frac{P}{Q} = \frac{l_1}{l_2} \)
Explanation
Interchanging the positions of galvanometer and cell in a balanced Wheatstone bridge (or metre bridge) does not affect the balance condition. The balance condition remains \( \frac{P}{Q} = \frac{l_1}{l_2} \).
