Question 551: 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 $$\mathrm{Q}$$.
