MCQ
The current flowing through $R _2$ is:
  • A
    $\frac{2}{3}\,A$
  • B
    $\frac{1}{4}\,A$
  • C
    $\frac{1}{2}\,A$
  • $\frac{1}{3}\,A$

Answer

Correct option: D.
$\frac{1}{3}\,A$
d
$R _{ eq }=4\,\Omega$
$i =\frac{8}{4}=2\,A$

$i _1=\frac{2 \times 3}{3+6}=\frac{2}{3}\,A$

$i _2=\frac{2 / 3}{2}=\frac{1}{3}\,A$
