Question

Find the effective resistance between A and B in the given figure

• A. $2\Omega$
• B. $4\Omega$
• C. $6\Omega$
• D. $8\Omega$

Answer 1

The correct option is C $6\Omega$

$30\Omega$ is in parallel with $6\Omega$, which will give $5\Omega$ as resultant.
Now, we get a balanced wheatstone bridge, where we can omit the combination of $5\Omega$ and $10\Omega$.

The remaining circuit gives us the resultant of $6\Omega$.
