A) \[10\,\Omega \]
B) \[20\,\Omega \]
C) \[40\,\Omega \]
D) None of the above three values
Correct Answer: A
Solution :
This is a balanced Wheatstone bridge. Therefore no current will flow from the diagonal resistance \[10\,\Omega \] \ Equivalent resistance \[=\frac{(10+10)\times (10+10)}{(10+10)+(10+10)}\]\[=10\,\Omega \]
