If two currents are in the same direction at any instant of time in a ...
Correct option is B
The resultant of the currents flowing in the same direction in a particular branch must be equal to the sum of the individual currents.
For example, 3A and 5A are the currents flowing in the same direction in a branch.
Resultant current flowing though the branch Itotal=3+5=8A
Thus option B is correct.

Net Current in a Circuit with Two Currents in the Same Direction
Introduction:
When analyzing circuits, it is important to understand the behavior of currents flowing through different branches. In some cases, multiple currents may flow in the same direction within a specific branch. This scenario raises the question of how these currents interact with each other and what the resulting net current is.
Explanation:
When two currents flow in the same direction at any given instant of time in a specific branch of a circuit, the net current at that instant is equal to the sum of the two currents.
Reasoning:
To understand why the net current is the sum of the two currents, let's consider the basic principles of current flow.
1. Kirchhoff's Current Law (KCL):
According to KCL, the sum of currents entering and leaving a node in a circuit must be equal to zero. In other words, the total current flowing into a node is equal to the total current flowing out of it.
2. Current Conservation:
In a closed circuit, current is conserved. It means that the total current entering a junction is equal to the total current leaving that junction.
Analysis:
Now, let's consider a branch in a circuit where two currents (I1 and I2) are flowing in the same direction at a particular instant of time.
1. Current I1:
- Enters the branch from one end.
- Flows through the branch.
- Leaves the branch from the other end.
2. Current I2:
- Enters the branch from one end.
- Flows through the branch.
- Leaves the branch from the other end.
Since both currents enter and leave the branch, the net current at that instant must consider the sum of the two currents.
Conclusion:
Therefore, when two currents flow in the same direction at any instant of time in a given branch of a circuit, the net current at that instant is the sum of the two currents. This can be explained using Kirchhoff's Current Law and the principle of current conservation.
