Questions & Step-by-Step Solutions

What happens to the total current in a parallel circuit if one of the branches is disconnected?
Correct Answer: Total current decreases.
  • Step 1: Understand that a parallel circuit has multiple branches where current can flow.
  • Step 2: Know that each branch allows electricity to flow independently.
  • Step 3: If one branch is disconnected, that path for current is removed.
  • Step 4: With one less path, the total amount of current that can flow through the circuit decreases.
  • Step 5: Therefore, the total current in the circuit is lower than it was before the branch was disconnected.
