Given below is a neat, labelled diagram to obtain balancing condition of Wheatstone bridge.

What is the galvanometer current when the bridge is balanced?

A

`I_(g)` flows from 'B' to 'D'

B

`I_(g)` flows from 'D' to 'B'

C

`I_(g)` has no significance in this case

D

`I_(g)=0`

Text Solution

Verified by Experts

The correct Answer is:
D
At balanced condition, there is no current flow through Galvonometer (BD).
i.e., `i_(g)=0`
