MCQ
The current in the adjoining circuit will be
  • A
    $\frac{1}{{45}}\,ampere$
  • B
    $\frac{1}{{15}}\,ampere$
  • $\frac{1}{{10}}\,ampere$
  • D
    $\frac{1}{5}\,ampere$

Answer

Correct option: C.
$\frac{1}{{10}}\,ampere$
c
(c) ${R_{{\rm{equivalent}}}} = \frac{{(30 + 30)30}}{{(30 + 30) + 30}} = \frac{{60 \times 30}}{{90}} = 20\,\Omega $

$\therefore i = \frac{V}{R} = \frac{2}{{20}} = \frac{1}{{10}}\,ampere$
