Resistors in Parallel Resistors being in parallel means their ends are connected by a conductor, making their ends at a common potential. That means exactly the same potential difference is across each of the resistors that are connected in parallel.

Consider this string of Christmas lights that are connected in parallel. What happens if one of the bulbs burns out or is removed?
