QAIPMT-2003-Ph-2723: NEET 2003 Physics - Class 12 AIPMT-2003-Ph-2723 Solution: In a Wheatstone's bridge all the four arms have equal…
In a Wheatstone's bridge 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 by the battery is
Multiple Choice Options
- A R/4
- B R/2
- C R
- D 2R
Step-by-Step Verified Solution
In balance Wheatstone bridge, the galvanometer arm can be neglected so equivalent resistance = R.
