Physics - Current Electricity Question with Solution | TestHub

Using Kirchhoff's current Law, Current flowing in = Current flowing out $\begin{array}{rl}& 10+2.5+5=6+\mathrm{x}\\ \therefore \mathrm{x}& =17.5-6\\ & =11.5\mathrm{A}\end{array}$ $\therefore$ Magnitude and direction of the current in 'OP' should be $11.5\mathrm{A}$ from $\mathrm{O}$ to $\mathrm{P}$.
