What happens to the current in a parallel circuit when more branches are added?.
- A.The current decreases in all branches.
- B.The total current increases.
- C.The current remains the same.
- D.The current is divided equally among branches.
Model answer
What a good answer should say
- The total current increases.
Explanation
Why this works
In a parallel circuit, adding more branches provides additional paths for the current to flow. As a result, the total current supplied by the source increases, while the current through each individual branch may vary depending on the resistance of that branch.
Therefore, the correct option is that the total current increases.
