C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Given circuit is a balanced wheatstone bridge. In balanced condition, no current flows through the galvanometer arm resistance i.e., 
. Thus, the given circuit can be redrawn as,
shown in figure.
Now, equivalent resistance of the circuit is,
Current drawn from the battery,
