If a parallel circuit is opened in the main line, the current_______________?
Correct answer: C. is zero in all branches
- A. increases in the branch of the lowest resistance
- B. increases in each branch
- C. is zero in all branches
- D. is zero in the highest resistive branch
Explanation
The main line supplies all parallel branches, so opening it disconnects the source from every branch. Consequently, the current is zero throughout the circuit.
