Question

The equivalent resistance between points $A$ and $B$ is

• A. $32.5\Omega$
• B. $22.5\Omega$
• C. $2.5\Omega$
• D. $42.5\Omega$

Answer 1

The correct option is B $22.5\Omega$

From above circuit,
$R_{eq}=2\Omega +\left(25\Omega ||50\Omega ||50\Omega \right)+8\Omega$
or $R_{eq}=2+12.5+8=22.5\Omega$
