Question

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:

• A. $\frac{R}{4}$
• B. $\frac{R}{2}$
• C. R
• D. 2R

Answer 1

Answer: (C)

R

Answer 2

Resistance seen by the battery = equivalent
resistance b/w A & B = R
