In a Wheatstone's brigde all the four arms have equal resistance `R`. If the resistance of the galvanometer arm is also `R`, the equivalent resistance of the combination as seen b the battery is

A

`2 R`

B

`(R )/(4)`

C

`(R )/(2)`

D

`R`

Text Solution

Verified by Experts

The correct Answer is:
D

Since, Wheatstone.s bridge is balanced, then resistance of galvanometer will be uneffective.
