In a four branch parallel circuit, 50mA current flows in each branch. If one of the branches opens, the current in other branches
- A. Increase, but not double.
- B. Decrease.
- C. Unaffected.
- D. Double.
Answer: C. Unaffected.
Explanation: In a parallel circuit each branch is across the same voltage, so the other branches' currents are unaffected.
