SATHEE: Current Electricity - Result Question 92

Current Electricity - Result Question 92

97. The metre bridge shown is in balance position with $\frac{P}{Q} = \frac{l_{1}}{l_{2}}$ . If we now interchange the position of galvanometer and cell, will the bridge work? If yes, what will be balance condition?

[NEET Odisha 2019]

(a) yes, $\frac{P}{Q} = \frac{l_{1}}{l_{2}}$

(b) yes, $\frac{P}{Q} = \frac{l_{2} - l_{1}}{l_{2} + l_{1}}$

(d) yes, $\frac{P}{Q} = \frac{l_{2}}{l_{1}}$

Show Answer

Answer:

Correct Answer: 97. (a)

Solution:

(a) For Balanced Bridge

$\frac{P}{Q} = \frac{l_{1}}{l_{2}}$

For balanced bridge (finally)

On interchanging galvanometer and battery positions, the balance condition remains unchanged.
