MCQ
The equivalent resistance between $A$ and $B$ is $......$
  • $\frac{2}{3} \Omega$
  • B
    $\frac{1}{2} \Omega$
  • C
    $\frac{3}{2} \Omega$
  • D
    $\frac{1}{3} \Omega$

Answer

Correct option: A.
$\frac{2}{3} \Omega$
a
$\frac{1}{ R _{ eq }}=\frac{1}{2}+\frac{1}{12}+\frac{1}{4}+\frac{1}{6}+\frac{1}{2}$

$=\frac{6+1+3+2+6}{12}=\frac{18}{12}=\frac{3}{2}$

$\Rightarrow \quad R_{ eq }=\frac{2}{3}\,\Omega$
