Five current carrying conductors meet at a point ' $\mathrm{O}$ ' as shown in figure. The magnitude and direction of the current in conductor ' $\mathrm{OP}$ ' is
$6.5 \mathrm{~A}$ from $\mathrm{O}$ to $\mathrm{P}$.
$9 \mathrm{~A}$ from $\mathrm{P}$ to $\mathrm{O}$.
$10.5 \mathrm{~A}$ from $\mathrm{P}$ to $\mathrm{O}$.
$11.5 \mathrm{~A}$ from $\mathrm{O}$ to $\mathrm{P}$.
Solution
Using Kirchhoff's current Law, Current flowing in = Current flowing out
$\begin{aligned}
& 10+2.5+5=6+\mathrm{x} \\
\therefore \quad \mathrm{x} & =17.5-6 \\
& =11.5 \mathrm{~A}
\end{aligned}$
$\therefore \quad$ Magnitude and direction of the current in 'OP' should be $11.5 \mathrm{~A}$ from $\mathrm{O}$ to $\mathrm{P}$.
