In a parallel circuit, the voltage across each branch must be greater than the previous.

In a parallel circuit, the voltage across each branch must be greater than the previous.

• A. True
• B. False
• C. Depends on source
• D. Always equal

Answer: (B)

In parallel circuits, all branches are connected across the same two points, so they share the same voltage. That means each branch experiences the same potential difference as the source; there isn’t a sequence where one branch’s voltage is greater than the next. The current in each branch can differ, depending on the branch’s resistance, via I = V/R for that branch. So the statement that the voltage across each branch must be greater than the previous isn’t accurate. The voltage across every branch is the same as the source voltage (in an ideal circuit). If you’re comparing how much current flows in different branches, that depends on each branch’s resistance, not on the voltage being different between branches.
