The voltage drop across any branch of a parallel circuit is the same as the applied voltage.

• A. Cannot be determined
• B. Depends on branch
• C. False
• D. True

Answer: (D)

In a parallel circuit, all branches connect across the same two points, so they share the same potential difference as the source. That means the voltage drop across every branch equals the applied voltage. The current in each branch can differ because it depends on that branch’s resistance (I = V/R), but the voltage across each branch remains the same. If the source is V, each branch has V across it, and the total current is the sum of the branch currents. This holds in ideal circuits; real wires may introduce tiny drops, but in standard AC/DC practice tests we treat the voltage across each parallel branch as equal to the applied voltage. Thus the statement is true.
