Question 522: Current Electricity

Question

Five current carrying conductors meet at point $\mathrm{P}$. What is the magnitude and direction of the current in conductor $\mathrm{PQ}$?

Accepted Answer

According to Kirchhoff's first law, at point $\mathrm{P}$,
$\begin{aligned}
& 5 \mathrm{~A}+4 \mathrm{~A}+\mathrm{I}-5 \mathrm{~A}-3 \mathrm{~A}=0 \\
& \mathrm{I}=-1 \mathrm{~A}
\end{aligned}$
$	herefore \quad I=-1 A$
1 A current flows from $\mathrm{P}$ to $\mathrm{Q}$.
