Question

An ideal ammeter is connected in a circuit as shown in circuit diagram. What wiil be the reading of ammeter (in S.l. units)

• A. $5$
• B. $7$
• C. $3$
• D. $9$

Answer 1

The correct option is B $7$

$\begin{array}{c}{i}_1=\frac{10}{2}=5A\\ i_2=\frac{10}{2}=5A\\ i_3=\frac{4}{2}=2A\\ \therefore i=i_2+i_3=7A\end{array}$

Hence,

option $\left(B\right)$ is correct answer.
