Solution
The correct option is D 6A from Q to P
Answer is D.
The explanation is given below.
The point Q is not mentioned, However answering it by keeping the end point of P as Q.
The currents, 2 A and 8 A combine as 10 A and flows out. This 10 A is split as 6 A and flows down and then as 4 A and flows up.
The 6 A is split as 4 A and 2 A at the bottom. The 4 A is split as 3 A and 1 A in the middle.
Therefore, the 3 A and 3 A flows towards P from Q.
Hence, a magnitude of 6 A flows in the direction from Q to P.
