In a parallel circuit, which statement is correct?

• A. The voltage across a branch is different for each device.
• B. Two or more devices are connected across the same source of electrical power.
• C. Only one path exists for current to flow.
• D. The total resistance is greater than any individual resistance.

Answer: (B)

In a parallel circuit, each device is connected across the same voltage source, so they all share the same potential difference. This is why the statement describing two or more devices connected across the same power source correctly captures how parallel circuits are arranged. The other ideas don’t fit: in parallel the voltage across each branch is the same, not different; multiple paths for current exist rather than only one; and the total resistance in parallel is not greater than any individual resistor (adding more paths lowers the total resistance, since 1/R_total = sum of 1/R_i).
