Question

Current coming from the battery and ammeter reading are

• A. $\frac{3}{8}A,\frac{1}{8}A$
• B. $\frac{1}{8}A,\frac{1}{8}A$
• C. $2A,\frac{2}{3}A$
• D. $2A,\frac{1}{8}A$

Answer 1

The correct option is A $\frac{3}{8}A,\frac{1}{8}A$

$\frac{x-0}{4}+\frac{x-2}{4}+\frac{x-0}{4}+\frac{x-0}{4}=0$

$\Rightarrow 4x=2$

$\Rightarrow x=\frac{1}{2}$

from battery : $i=\frac{2-x}{4}=\frac{3}{2\times 4}=\frac{3}{8}A$

From A : $i=\frac{x}{4}=\frac{1}{8}A$

Hence, option $A$ is correct answer.
