In the circuit shown, some potential difference is applied between A & B. The equivalent resistance between A & B is
Answer & explanation
Correct answer: option 3
This is a balanced wheat stone bridge. SO there is no potential difference across 5$\Omega$.
9 $\Omega$ and 6 $\Omega$ are in parallel
Equivalent resistance is $\frac{9\times 6}{9+6}$ = 3.6$\Omega$
