Question

The current I in the circuit shown below is

• A. $\frac{1}{45}A$
• B. $\frac{1}{15}A$
• C. $\frac{1}{10}A$
• D. $\frac{1}{5}A$

Answer 1

The correct option is C $\frac{1}{10}A$

Hence, option $C$ is correct answer.

$30\Omega$ and $30\Omega$ are in seller

$\therefore Req=60\Omega$

(2) Now $60\Omega$ and $30\Omega$ are in parallel

$\therefore Req=\frac{1}{60}+\frac{1}{30}$

$=\frac{60}{3}=20\Omega$

By $v=1R$

$1=\frac{V}{R}=\frac{2}{20}=\frac{1}{10}=0.1A$
