In a parallel circuit, what happens when one branch is removed?

• A. Removing a branch changes the voltage across the remaining branches.
• B. The total current stays the same when a branch is removed.
• C. The currents in the remaining branches reconfigure to increase the voltage across them.
• D. Removing a branch reduces the total current, while the voltage across the remaining branches stays the same.

Answer: (D)

In a parallel circuit, the voltage across each branch is the same as the source, and each branch draws current independently. Removing one branch eliminates a path for current, so the total current drawn from the source decreases. The voltage across the remaining branches stays the same, assuming an ideal voltage source, because the supply maintains the same voltage across the parallel network. The currents in the remaining branches may change in magnitude based on their resistances, but the branch voltages remain unchanged.
