A) \[5\Omega \]
B) \[7\Omega \]
C) \[14\Omega \]
D) \[35\Omega \]
Correct Answer: B
Solution :
The circuit is redrawn as below: It is a typical case of unbalanced bridge. If\[\frac{P}{Q}=\frac{S}{R}=n\]then learn following standard result: \[{{R}_{eq}}=\left( \frac{3n+1}{n+3} \right)r\] Here, \[{{R}_{eq}}=\frac{7}{5}\times 5=7\]You need to login to perform this action.
