Kirchhoff's Laws & Measuring Instruments

Five current carrying conductors meet at a point ' $\text{O}$ ' as shown in figure. The magnitude and direction of the current in conductor ' $OP$ ' is

Show answer and solution

Answer: (d)

Junction rule at O: total current in = total current out.
In: $10 + 2.5 + 5 = 17.5\text{ A}$ ; out: $6\text{ A}$ .
$I_{OP} = 17.5 - 6 = 11.5\text{ A}$ , flowing out of O.
So the answer is (d) 11.5 A from O to P.
