Question

The equivalent resistance between the points $A$ and $B$ in the circuit shown in the following figure is

• A. $10\Omega$
• B. $20\Omega$
• C. $30\Omega$
• D. $40\Omega$

Answer 1

The correct option is C $30\Omega$

By rearranging the given circuit with only the relevant resistors,

Equivalent resistance between $A$ and $B$ is
$\Rightarrow R_{AB}=30\Omega$
