A) R
B) 2 R
C) 4 R
D) 8 R
Correct Answer: B
Solution :
Due to symmetry about line AB network can be represented as Equivalent resistance \[=2R\] \[\frac{1}{V}+\frac{1}{-20}=\frac{-1}{15}\] \[\frac{1}{V}=\frac{1}{20}-\frac{1}{15}\]\[\frac{1}{V}=\frac{3-4}{5\times 12}=-\frac{1}{60}\]You need to login to perform this action.
