In a parallel circuit, the voltage across each branch is

• A. The same
• B. It doubles in each branch
• C. It is zero
• D. It varies with branch resistance

Answer: (A)

In a parallel circuit, all branches are connected across the same two points, so the voltage across each branch is the same as the source voltage. This happens because every path shares the same two nodes, giving each path the same potential difference regardless of its own resistance. The current, however, divides among the branches according to each branch’s resistance, following I = V/R. So a branch with lower resistance draws more current, while a higher-resistance branch draws less, but the voltage across every branch stays equal to the supply. The other statements don’t fit: the voltage doesn’t double in each branch, isn’t zero, and does not vary with branch resistance in an ideal parallel circuit.
