Figure 6.64 shows a balanced wheatstone bridge.

A

If `P `is slightly increased, the current in the galvanometer flows from `C` to `A`.

B

If `P `is slightly increased, the current in the galvanometer flows from `A` to `C`.

C

If `Q `is slightly increased, the current in the galvanometer flows from `C` to `A`.

D

If `Q` is slightly increased, the current in the galvanometer flows from `A` to `C`.

Text Solution

Verified by Experts

The correct Answer is:
B, C
If `P` is slightly increased, potential of `C` will decrease.
Hence, current will flow from `A` to `C`
If `Q` is slightly increased, potential of `C` will increase, hence current will flow `C` to `A`.
