A) Between the points B and D is R
B) Between the points B and D is \[\frac{R}{2}\]
C) Between the points A and C is R
D) Between the points A and C is\[\frac{R}{2}\]
Correct Answer: B , C
Solution :
\[\frac{1}{{{R}_{BD}}}=\frac{1}{2R}+\frac{1}{R}+\frac{1}{2R}\Rightarrow {{R}_{BD}}=\frac{R}{2}\] Between A and C circuit becomes equivalent to balanced Wheatstone bridge so \[{{R}_{AC}}=R\].Solution :
\[\frac{1}{{{R}_{BD}}}=\frac{1}{2R}+\frac{1}{R}+\frac{1}{2R}\Rightarrow {{R}_{BD}}=\frac{R}{2}\] Between A and C circuit becomes equivalent to balanced Wheatstone bridge so \[{{R}_{AC}}=R\].You need to login to perform this action.
