Question

The resistance between points M and N in the circuit is

• A. $24\Omega$
• B. $48\Omega$
• C. $64\Omega$
• D. $4\Omega$

Answer 1

The correct option is B $48\Omega$


$R_2,R_3$ in series $R^{\prime }=R_2+R_3=32\Omega$
$R_5,R_6$ in series $R"=R_5+R_6=32\Omega$
$R^{\prime },R"$ are in parallel $R"=16\Omega$
$R^{\prime },R"$ are in parallel R" are in series = $R_1+R"+R_4$
$16+16+16=48\Omega$
