Question

Find the current through $2\text{V}$ battery.

• A. $2\text{A}$
• B. $4\text{A}$
• C. $3\text{A}$
• D. $1\text{A}$

Answer 1

The correct option is D $1\text{A}$

Distribution of current in the circuit is given below.


Applying Kirchhoff's second law in loop $1\text{(ABEFA)}$,

$-4i_1+4-2i_1+2=0$

$\Rightarrow 6i_1=6$

$\therefore i_1=1\text{A}$

So, current passes through $2\text{V}$ battery is $1\text{A}$.

Hence, option $\left(a\right)$ is correct.
