Model Answer

The potential difference across each individual resistor is the same and equals V (the battery's potential difference).

Source: Chapter 11, Section 11.6.2 – Resistors in Parallel

Explanation

In a parallel combination, all resistors share the same two endpoints, so the same potential difference V appears across each one. Examiners expect the student to state clearly that each resistor has potential difference equal to V (the battery voltage), not just that they are "equal." One crisp line with the key term is sufficient for 1 mark.
