MCQ
In the given figure, when galvanometer shows no deflection, the current (in $A$) flowing through $5\,\Omega $ resistance will be
  • A
    $0.5$
  • $0.6$
  • C
    $0.9$
  • D
    $1.5$

Answer

Correct option: B.
$0.6$
b
Let current through $5\,\Omega $ resistance be $i$.

Then  $i \times 25 = (2.1 - i)\,10$

$i = \frac{{10}}{{35}} \times 2.1 = 0.6\,A$
