Question

The effective resistance between the points $A$ and $B$ in the figure is

• A. $5\Omega$
• B. $2\Omega$
• C. $3\Omega$
• D. $4\Omega$

Answer 1

Answer: (B)

$2\Omega$

Answer 2

Given circuit is equivalent to

So the equivalent resistance between points A and B is equal to $R = \frac{6 \times 3}{6 + 3} = 2\Omega$
