Question

A balanced wheatstone bridge is shown in the value of currents $i_1$ and $i_2$ are

• A. $0.9A$ and $0.6A$
• B. $0.3A$ and $0.2A$
• C. $0.5A$ and $0.7A$
• D. $0.7A$ and $0.6A$

Answer 1

The correct option is A $0.9A$ and $0.6A$

$\begin{array}{c}{R}_{eq}=\frac{9\times 6}{9+6}+0.4\\ =\frac{54}{15}+0.4\\ =3.6+0.4\\ =4\Omega \\ Now,\\ \Rightarrow i=\frac{6}{4}=1.5\\ \therefore i_1=\frac{1.5}{15}\times 9\\ 0.9A\\ Hence,optionAiscorrectanswer.\end{array}$
