In a five-branch parallel circuit, there are 12 mA of current in each branch. If one of the branches opens, the current in each of the other four branches is_______________?
Correct answer: B. 12 mA
- A. 48 mA
- B. 12 mA
- C. 0 A
- D. 3 mA
Explanation
In a parallel circuit, each branch has the same source voltage, so the current in an unchanged branch remains 12 mA when another branch opens. Only the total source current falls, from 60 mA to 48 mA.
